You would need to access the console of your web server. Then, edit the file called default-constants.php

nano /home/beautifulnara/public_html/wp-includes/default-constants.php

Go to the line the writes WP_MAX_MEMORY LIMIT

Then, under the else condition, change the value from 256M (default) to 1024M.
For example,

define( ‘WP_MAX_MEMORY_LIMIT’, ‘1024M’ );

To verify, there will be a noticeable change upon navigating from an option to another within the WordPress backend.

Next, some modification are to be done on your WHM (Web Host Manager). Once you have logged in, navigate to Home > Software > MultiPHP Manager.

Before adding the values in, ensure you have calculated the remaining free memory in your server which can be allocated for PHP-FPM.

In our case, the new values for the PHP-FPM Pool Option will be: –

Max Requests: 300
Process Idle Timeout: 10
Max Children: 100

At the searchbar on left pane, type php.

Select PHP-FPM service for Apache, and then hit Yes.
