Step 5: Click on the “Save Change” button and reload your website to check if the error is gone.

Method 2: Edit your .htaccess file

If you don’t have access to php.ini, you can edit your .htaccess file by implementing the following steps:

Step 1: Open your file manager.

Step 2: Locate the .htaccess file in the public_html directory

Step 3: Right-click and select Edit

Step 4: Add the following code to a .htaccess file

php_value memory_limit 64M

Method 3: Deactivate and reactivate all plugins

Increasing the PHP memory limit will certainly help you fix memory exhaustion. However, you also need to check all your installed plugins on your website. Since they are also the major reason causing this error.

To do that, first of all, you need to deactivate all plugins and then reactivate them one by one to find the cause.

Step 5: Now, you need to go back to the wp-content folder to remove the empty folder created earlier. Then rename the plugins-error folder back to “plugins“. This will restore all your plugins on your website without reactivating them.

Step 6: You can log in to the WP dashboard and go to the Plugins page to activate all plugins one by one to see which one is causing the error.

If you get the error again, which means that the error will be caused by the last plugin you just reactivated.
