Background of the issue:
I followed the steps in your email and updated the WPML Plugin to version 4.6.15 and then updated Elementor to version 3.26. We are still experiencing a Critical Error. The issue can be seen at: hidden link
Symptoms:
I am still receiving a Critical Error on the site after updating. Note that the site has been reverted to Version 4.6.14 until a solution is found.
While one of my teammates takes care of your ticket, I will provide you with the first debugging steps.
You need to see what the errors are. Guessing what might be the problem and trying different solutions may lead to even more trouble. The first step is to enable debug. You can do this by adding a few lines to the site’s wp-config.php file. With error log enabled, you will see what the actual problem is.
To enable it, open your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:
define('WP_DEBUG', true);
In order to enable the error logging to a file on the server you need to add yet one more similar line:
define( 'WP_DEBUG_LOG', true );
In this case, the errors will be saved to a debug.log log file inside the /wp-content/directory.
