When encountering the “Allowed Memory Size Exhausted” fatal error in WordPress, it indicates that your WordPress installation is trying to use more memory than is allocated by the server. This can happen for various reasons, such as poorly optimized plugins or themes, or just because your site has grown and needs more resources. Here are the steps to troubleshoot and fix this issue
Understanding the Error Message:
Common Causes of the Error:
Inefficient Code: Poorly optimized or inefficient themes and plugins can lead to increased memory consumption, triggering the error. This is especially common when using resource-intensive plugins or themes.
Large Datasets: Processing large amounts of data, such as extensive image galleries or large databases, can strain server resources and exceed the allocated memory limit.
Server Configuration: The server’s PHP configuration may have a relatively low memory limit. This is common in shared hosting environments where server resources are distributed among multiple users.
Troubleshooting Steps:
-
- Identify the Culprit:
- Start by deactivating all plugins and switching to a default WordPress theme (such as Twenty Twenty-One).
- Reactivate each plugin one by one and switch themes to pinpoint the one causing the memory exhaustion.
- Increase Memory Limit:
- Edit the
wp-config.phpfile in your WordPress root directory. - Add the following line of code just before the “/* That’s all, stop editing! */”
- Edit the
- Identify the Culprit:
define('WP_MEMORY_LIMIT', '256M');
Adjust the memory limit value as needed.
PHP.ini Configuration:
- If you have access to the server’s PHP configuration, locate and edit the
php.inifile. - Increase the memory limit by modifying the
memory_limitdirective, e.g.,memory_limit = 256M.
- If you have access to the server’s PHP configuration, locate and edit the
memory_limit = 256M
htaccess Modification:
- Add the following line to your site’s
.htaccessfile:
- Add the following line to your site’s
php_value memory_limit 256M
- If you’re on shared hosting, contact your hosting provider and request a higher memory limit.
