Increasing the PHP Memory Limit in WordPress

One common problem WordPress users might encounter is the WordPress Memory Exhausted Error. This issue can be frustrating, but the good news is that it’s often simple to fix by increasing the PHP memory limit in WordPress. In this section, I’ll walk you through the steps you can take to address this issue and get your site back on track.

The primary cause of the memory exhausted error is when WordPress requires more memory than the default PHP memory limit set by your hosting provider. This can occur due to poorly optimized themes or plugins, or when you’re running resource-intensive tasks on your site. While this error might seem similar to other errors like the Internal Server Error or Error Establishing a Database Connection, troubleshooting the memory exhausted error focuses on increasing the available PHP memory limit.

To increase the PHP memory limit in WordPress, follow these steps:

1. Edit the wp-config.php file: Locate the wp-config.php file in your WordPress installation’s root directory. Open it using a text editor, and look for the line that says define('WP_MEMORY_LIMIT', '64M');. Increase the memory limit value to a higher number (e.g., ‘128M’) and save the changes. If the line is not present, you can add it just before the /* That's all, stop editing! Happy publishing. */ line.
2. Modify the .htaccess file: If editing the wp-config.php file doesn’t work, try increasing the memory limit in your .htaccess file. Access the file in your WordPress root directory, and add the following code:

   php_value memory_limit 128M

You can change the value to fit your needs.

3. Update the php.ini file: In some cases, you might need to modify the php.ini file (usually found in the root folder of your hosting server) to fix the memory exhausted error. Open the file and look for the line that reads memory_limit = 64M;. Increase the value to a higher number and save your changes.

While increasing the PHP memory limit can solve the memory exhausted error, it’s essential to note that it’s not always the best long-term solution. Poorly optimized themes, plugins, and other issues might still cause your site to consume excessive resources. In such situations, it’s better to troubleshoot the root cause, which might include:
