Can you provide more information on what exactly breaks on your site?
Do you have for an example some errors in your debug log?
If you have not enabled debug logging to catch the possible errors, you can do it by setting this options 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 will generate a debug.log file in wp-content folder and if you have errors there, they might help me and my colleagues to diagnose and be of better assistance in solving the issue that you are experiencing.
