Increasing PHP memory limit

Sometimes the internal error can be caused due to less PHP memory limit. In order to increase the PHP memory limit in WordPress, First, edit the wp-config.php file on your WordPress site. It is located in the WP root folder and you will need to use an FTP client or file manager in your web hosting control panel.

If this does not work for you, then your web hosting provider does not allow you to increase your PHP memory limit manually.

If you are seeing the internal server error only when you try to login to your WordPress admin or upload an image in your wp-admin, then you should increase the memory limit by following these steps:

Create a blank text file called php.ini
Paste this code in there: memory=64MB
Save the file
Upload it into your /wp-admin/ folder using FTP

We recommend you get the server logs from your WordPress web hosting provider that can help you find the exact cause of exhausting your memory limit.

If increasing the PHP memory limit doesn’t solve your issue, then you have to do some more troubleshooting.

If checking for the corrupt .htaccess file and increasing the PHP memory limit doesn’t solve your problem, then the issue might be something related to a specific plugin or a conflict between the combination of plugins that are not working fine with each other.

For checking this you can deactivate all the plugins at once. If disabling all the plugins will resolve the error, then it confirms that one of the plugins is causing the error. Now activate those plugins one by one to find the plugin which is causing the internal error. Once you find the plugin, get rid of it and report the error to the plugin author
