But no need to worry – I’m here to help you understand what causes this error and guide you through the steps to resolve it.
Though HTTP Error 500 may seem intimidating, it’s just a generic error message that appears when the server encounters an issue. Since it doesn’t pinpoint a specific problem, it’s essential to troubleshoot various potential causes. Don’t let that stress you out, though – I’ll walk you through optimizing your website, one step at a time.
First, let’s discuss the common reasons behind the WordPress HTTP Error 500 and then dive into the solutions to set your site back on track. By understanding the root of the issue, you’ll be better equipped to prevent it from happening again, allowing you to focus on creating quality content for your website. Stay with me as I unravel the mysteries behind this pesky error!
Understanding the HTTP Error 500
I’ve come across HTTP Error 500 in WordPress a few times, and it’s no fun. It’s a generic message indicating an internal server error, which makes it challenging to diagnose the root cause. To provide some context, let’s understand what this error is and why it occurs.
The HTTP Error 500 is a server-side issue that happens when your WordPress site can’t be accessed or loaded properly. The server encounters a problem while processing the request and fails to display your content. It’s essential to note that this error is not unique to WordPress and can occur on any website.
There’s a variety of reasons that can trigger HTTP Error 500, each with its own set of solutions. Some common culprits include:
- Incorrect .htaccess files: A syntax error or misconfigured directive can halt your server.
- Plugin or theme issues: Conflicts between themes and plugins can lead to this error.
- Exhausted memory: Your site might hit the memory limit, especially on shared hosting environments.
- Server configuration problems: Errors in server configuration files (e.g., php.ini) can disrupt your site’s functionality.
Apart from these, there might be other less common reasons, such as incorrect file permissions, a crashed database, or even corrupted files that require attention.
It’s crucial to troubleshoot the HTTP Error 500 methodically. Since it’s a server-side issue, you’ll want to check your server logs for any indication of the problem. You can find these logs in your hosting account’s control panel or by reaching out to your hosting provider’s support team.
In addition, you can test common causes one by one, starting with the most likely culprits. For example, replacing your .htaccess file with a default one could resolve the issue if it’s caused by an error in that file. Similarly, you can test if a plugin or theme conflict is causing the problem by disabling them temporarily.
While you’re tackling the HTTP Error 500, it’s not uncommon to encounter other errors as well. Some related errors you might stumble across include the WordPress Parse error, the WordPress Memory Exhausted Error, and cases where WordPress gets stuck in Maintenance Mode.
Keep in mind that addressing the HTTP Error 500 might take some time and patience. There’s no one-size-fits-all solution for this issue, which is why it’s crucial to stay persistent and follow a step-by-step approach. As you eliminate potential causes, you’re bound to find the one affecting your website and restore its normal functioning.
Common Causes of WordPress HTTP Error 500
Experiencing an HTTP Error 500 on your WordPress site can be quite a headache. This error is a common issue that often stems from various factors. As an expert blogger, I have encountered a fair share of these errors over time. To help you identify the root of this problem, I have listed some of the most common causes below.
One primary reason for the HTTP Error 500 is incorrect file permissions. Your server requires specific permission settings to read and execute files. If these settings are not accurate, you might encounter this error.
Another possible culprit is a corrupted .htaccess file. This essential file manages your website’s URL structure and redirects. If there’s an issue with the file, it could lead to the HTTP Error 500. You can easily fix this by renaming or removing the problematic file.
Plugin conflicts also contribute to the HTTP Error 500. Often, installing a new plugin or updating an existing one can cause the error. To solve it, try deactivating your plugins one by one, and identify the one causing the issue.
Similarly, themes on your WordPress site can also be a cause for the HTTP Error 500. Some themes might not be compatible with the latest version of WordPress, or they may conflict with plugins or custom code. You can troubleshoot this issue by switching to another theme, such as the default WordPress theme, and checking if the error persists.
An exhausted PHP memory limit might lead to this error as well. Insufficient memory could prevent your WordPress site from running some elements and functions. To fix it, you can increase your site’s memory limit. You can find more information on how to do this in this article on WordPress memory exhausted error.
Lastly, server configuration issues like PHP time-outs or syntax errors might cause the HTTP Error 500. A knowledgeable developer or your hosting provider might help you address such server-side issues.
In summary, the common causes for WordPress HTTP Error 500 include:
- Incorrect file permissions
- Corrupt .htaccess file
- Plugin conflicts
- Theme issues
- Exhausted PHP memory limit
- Server configuration issues
To solve the HTTP Error 500, it’s crucial to identify the root cause and address it accordingly. Check out our article on internal server error in WordPress for further assistance on fixing this error.

HTTP Error 500, commonly known as the Internal Server Error, can be a major roadblock to your WordPress site’s smooth functioning. But don’t worry! I’ve got you covered with these effective troubleshooting tips to help you fix it.
1. Check server logs
The first thing you should do is check your server logs. These logs contain valuable information about what might have caused the error. Contact your hosting provider if you’re unsure how to access them.
2. Update WordPress, themes, and plugins
Outdated software might be the culprit. Ensure your WordPress installation, themes, and plugins are all up to date. This will help you avoid any compatibility issues that could cause the HTTP Error 500.
3. Increase PHP memory limit
A common reason for this error is an exhausted PHP memory limit. Learn how to increase the WordPress memory limit to tackle this issue head-on.
4. Deactivate plugins
Faulty plugins can also trigger the HTTP Error 500. To narrow down the culprit, try deactivating all plugins and see if the issue persists. If it resolves, reactivate the plugins one by one until you find the problematic one.
5. Switch to a default theme
A problematic theme could be the cause. To check, temporarily switch to a default WordPress theme such as Twenty Twenty-One. If the error vanishes, you’ll know it’s time to update or change your theme.
6. Check for syntax errors
In some cases, the error might occur due to a syntax error. If you recently edited any PHP files, double-check them for any coding mistakes. The WordPress parse error guide can help you spot and fix these issues.
7. Repair the database
A corrupt database can trigger the HTTP Error 500. Use the built-in repair tool within WordPress to fix it. Don’t forget to create a backup before proceeding with this step.
8. Re-upload core files
If nothing else works, try re-uploading the WordPress core files. Download a fresh copy of WordPress and upload it to your server, ensuring that you don’t overwrite the wp-content folder and wp-config.php file.
9. Consult your hosting provider
If all else fails, it’s time to seek professional help from your hosting provider. They might be able to identify and fix server-side issues causing the error.

Increasing PHP Memory Limit
When troubleshooting the WordPress HTTP Error 500, one possible cause to consider is the PHP memory limit. Insufficient memory can lead to this error, and I’ll show you how to increase the PHP memory limit to help resolve the issue.
One method to increase the PHP memory limit is by editing the wp-config.php file. Follow these steps:
- Access your WordPress files using your favorite FTP client or cPanel file manager.
- Locate and open the wp-config.php file.
- Add the following line of code at the very bottom of the file, right before the line that says
/* That's all, stop editing! Happy publishing. */:
By doing this, you’ve increased the PHP memory limit to 256 MB. Save the changes, and you should see some improvement if the memory limit was the cause of the error.
Another method to increase the PHP memory limit is by editing the .htaccess file. This can be particularly helpful if the wp-config.php file modifications didn’t solve the problem. Just like before, locate and open the .htaccess file and add the following code at the very bottom:
php_value memory_limit 256M
After saving the changes, you should again see an improvement if the memory limit was affecting your site.
However, sometimes these methods may not work, especially if your hosting provider restricts PHP memory limit changes. In this case, it’s worth contacting their support team for assistance.
Increasing the PHP memory limit is just one of the solutions for addressing the WordPress HTTP Error 500. If this method doesn’t work for you, don’t worry; there are other techniques available to fix the issue. Just be patient and methodical in your troubleshooting process, and you’ll be back up and running in no time.
Deactivating Plugins and Themes- A Solution to WordPress HTTP Error 500
Deactivating plugins and themes is a troubleshooting method that’ll help you find if there’s an incompatibility or malfunction causing the dreaded WordPress HTTP Error 500. I’ll guide you through the necessary procedure.
The first step in resolving this issue is to deactivate all the WordPress plugins. To do this, log in to your site’s File Manager or use an FTP client. Then, navigate to the wp-content folder and locate the plugins folder. Rename this folder to something like plugins_deactivated. This action deactivates all your plugins in one go. Next, check if your site is working without the HTTP error 500. If it does, then your suspicion about a plugin causing the issue was right.
Let’s find out which plugin is the troublemaker. Reactivate the plugins one by one, by renaming the folder back to plugins and switching on each plugin individually through the WordPress dashboard. Ensure that you check your site after activating each plugin. The moment the error reappears, you’ve found the culprit.
Consider looking for an alternative plugin or contacting the plugin developer for a possible solution. Remember that outdated plugins are often the cause of such issues. Keep them updated to prevent future errors.
Now, let’s turn our attention to WordPress themes. Themes are vital in how your website looks and operates. But sometimes, themes can cause HTTP error 500 as well. To investigate if a theme is the problem, follow these steps:
- Access your WordPress dashboard and go to Appearance > Themes
- Switch to the default WordPress theme like Twenty Twenty-One (if it’s not installed, you’ll need to install and activate it)
- Check if the HTTP error 500 persist. If not, the issue was caused by your previous theme
To fix it, you can either contact the theme developer or search for a different theme to use on your site. Also, remember to keep your themes updated to avoid incompatibilities and errors.
By following this process, I hope you’ll be able to resolve the WordPress HTTP Error 500. Additionally, you might want to check other issues like the WordPress parse error, WordPress being stuck in maintenance mode, or WordPress memory exhausted error to further optimize your site’s performance. In case you want to resolve issues related to email services, you can learn from WordPress not sending email troubleshooting tips.

Checking the .htaccess File
Sometimes, the HTTP Error 500 in WordPress can be caused by .htaccess file issues. It’s a hidden file that manages URL redirects, permalinks, and server configuration settings. In this section, I’ll show you how to check and fix your .htaccess file to resolve the error.
First things first, you’ll need to access your website’s files using an FTP client or your web hosting control panel’s file manager. If you’re unfamiliar with using an FTP client, you can refer to this guide for step-by-step instructions.
Once you’ve accessed your site’s files, look for the .htaccess file in your website’s root directory. It’s usually located in the same folder as your wp-content, wp-admin, and wp-includes folders. Keep in mind that it’s a hidden file, so make sure your file manager is configured to show hidden files.
After locating the .htaccess file, follow these steps:
- Create a backup of your .htaccess file by downloading it to your local computer.
- Delete the original .htaccess file from your website’s root folder.
- Visit your WordPress dashboard and navigate to Settings > Permalinks.
- Click Save Changes to generate a new .htaccess file automatically.
By performing these steps, you’ll create a fresh .htaccess file with the default WordPress settings. This should fix the HTTP Error 500 if it was caused by issues with the .htaccess file.
However, if the error persists, it could be due to other factors such as plugin or theme conflicts, or issues with your website’s PHP memory limit, memory exhausted errors, or syntax errors. Be sure to investigate these potential causes and use the appropriate troubleshooting methods.
Lastly, note that even after resolving the error, there might be residual issues such as your WordPress getting stuck in maintenance mode or WordPress not sending email. Don’t worry – just follow the provided solutions to get your site up and running smoothly again.
By checking and fixing your .htaccess file, you’ll be one step closer to resolving the HTTP Error 500 and getting your WordPress site back on track. Don’t forget to explore other possible causes of the error and apply the necessary fixes to ensure long-term success.
Updating WordPress Core Files
One of the first steps I take when dealing with the WordPress HTTP Error 500 is updating my WordPress core files. It’s important to keep WordPress up-to-date to avoid potential issues and ensure optimal performance. The process can be accomplished by following these steps:
- Create a backup: Before updating WordPress core files, I always create a backup of my website. This ensures a safe fallback if anything goes wrong during the updating process.
- Download the latest version: To get started, I’ll download the latest version of WordPress from the official website. This ensures that I have access to the most recent and secure files available.
- Deactivate plugins and themes: I always deactivate all plugins and themes before proceeding with the update. This helps to avoid conflicts or issues that may arise from incompatible files or code.
- Replace core files: With everything deactivated, I can now replace the old WordPress files with the new ones. I upload the latest files, making sure to avoid overwriting the
wp-contentfolder and the
wp-config.phpfile, as these contain essential data for my website.
- Update the database: After updating the core files, there might be updates needed for the database as well. Usually, WordPress automatically prompts me to perform these updates after I log in to the dashboard.
Please note, if you’re still encountering the HTTP Error 500 after updating the core files, it could be due to other issues like:
- A syntax error in your code
- Your website being stuck in maintenance mode
- Running into a memory exhausted error
- Emails not being sent due to misconfiguration
- A general internal server error not specific to WordPress.
In conclusion, keeping WordPress core files up-to-date is a crucial step to avoid HTTP Error 500 issues. Always remember to create a backup before making any significant changes, deactivate your plugins and themes prior to replacing the files, and ensure you have the latest version of WordPress. With a careful and thorough approach, you’ll minimize the likelihood of encountering the dreaded HTTP Error 500.
If you’ve tried everything but the WordPress HTTP Error 500 still persists, you might consider reinstalling WordPress as a last resort. While it’s not a decision to be taken lightly, it’s sometimes necessary to eradicate stubborn issues. Before proceeding, always remember to backup your website’s data.
The first step to reinstalling WordPress is deleting old files. Start by accessing your website’s server through an FTP client or your web hosting control panel and locate the WordPress installation directory. Once you’ve found it, delete both the WordPress core files (except the ‘wp-config.php’ file) and the ‘wp-admin’ and ‘wp-includes’ folders.
Now, you’ll need to download a fresh copy of WordPress. Head over to the official WordPress website and download the latest version. Extract the files locally and upload them to your server via FTP or through your hosting control panel.
To ensure that your site’s content and settings are preserved during the reinstall process, be very careful not to overwrite the ‘wp-config.php’ file, as well as the ‘wp-content’ folder.
After uploading the new WordPress files, it’s time to update your database. Navigate to the WordPress admin area, and you’ll likely encounter a notification prompting you to update your database. Follow the on-screen instructions to complete the process.
Once you’ve reinstalled WordPress and updated the database, test your site to see if the HTTP Error 500 has been resolved. If the error persists, there may be other underlying issues at play, such as parse errors, your site being stuck in maintenance mode, a memory exhausted error, email-related issues, or another form of internal server error.
Remember, reinstalling WordPress should be considered as a final measure, and it’s critical to backup your site’s data before proceeding. Exploring alternative solutions and consulting with professionals can help you resolve more straightforward issues without the need for a complete reinstall.
