Error 500 and offset page layout

This thread is resolved. Here is a description of the problem and solution.

Problem:
The client reported a 500 error on their website after installing the WPML plugin. They also noted that their homepage and other pages were out of sync in the English version, and the Rest API was disabled without their intervention.
Solution:
We addressed the 500 error by suggesting the client enable the WP debug log to identify specific error messages. For instructions on enabling the WP debug log, we recommended visiting https://developer.wordpress.org/advanced-administration/debug/debug-wordpress/.
Additionally, we resolved the issue by adding specific code to the

functions.php

file in the theme folder. The necessary code and instructions can be found at https://wpml.org/faq/why-is-htaccess-getting-overwritten-with-the-language-folder-on-my-wpml-website/.

If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If further assistance is needed, please open a new support ticket at WPML support forum.

karimI-2	Hello, I just bought the plugin, unfortunately I have several problems. If I can't get it to work, I'll have to ask for a refund. I hope you can help me, because I'd like to be able to translate my site into English. As you can see from the images, I have a 500 error that I can't resolve. In addition, my home page and other pages on my site are out of sync and display differently in the English version. Finally, I checked my settings and it says that the Rest API is disabled. But I don't understand why, as I haven't activated any particular security. Thanks in advance for your help, PS: I made a mistake by creating a duplicate on the French forum Please take this ticket into account New threads created by Long Nguyen and linked to this one are listed below: https://wpml.org/forums/topic/i-checked-my-settings-and-it-says-that-the-rest-api-is-disabled/

We limit one issue per ticket only so I will split your other issues into new tickets for better handling. In this ticket, I will focus on the 500 error. Please let me know where you see the error, in the admin area, frontend, or a specific page. You can enable WP debug log, revisit that page and check if there is an error message in the log file and share it with me. If you don't know how to enable WP debug log, please follow the documentation https://developer.wordpress.org/advanced-administration/debug/debug-wordpress/ Looking forward to your reply. Thanks

It would be better to have a testing site where the issue is replicated. Your next reply is set to private to share the info. ❌ IMPORTANT: Please backup your database and website before proceeding ❌ You can use this plugin to create the backup: https://wordpress.org/plugins/duplicator/ ✙ I would need your permission to de-activate and re-activate Plugins and the Theme to change configurations on the site if needed. This is also a reason the backup is critical. Looking forward to your reply. Thanks

karimI-2	Thank you, the error 500 has been resolved. But as mentioned in my first message, why are the home page and other pages offset when I go to the English version? There's a problem with the layout of the blocks.
