Hello, in order to debug this issue I would need more information.
As a first step, would you mind to please enable debug in WordPress?
You can do this by setting/or replacing this options if it is already set in wp-config.php
// Turn debugging on
define('WP_DEBUG', true);
// Tell WordPress to log everything to /wp-content/debug.log
define('WP_DEBUG_LOG', true);
// Turn off the display of error messages on your site
define('WP_DEBUG_DISPLAY', false);
// For good measure, you can also add the follow code, which will hide errors from being displayed on-screen
@ini_set('display_errors', 0);
This should create a debug.log file inside /wp-content/ directory when an error appears. Please try to duplicate the issue when you enable logging.
As a first suggestion, shooting in the dark, I would suggest you to increase the memory dedicated to WordPress to at least 128mb. You can do this by set or change if already exists in wp-config.php
define( 'WP_MEMORY_LIMIT', '128M' );
Let me know of your progress.
