Links not working on the translated site

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

Problem:
The client is experiencing an issue where all links on the translated version of their site lead to an error 500, although these links work fine when opened in a new tab. There are no PHP or WordPress errors showing in the debug logs.
Solution:
First, we recommend ensuring that debugging is properly enabled in WordPress. To do this, open your

wp-config.php

file and locate the line

define('WP_DEBUG', false);

. Change it to:

define('WP_DEBUG', true);

Additionally, to log these errors to a file, add:

define('WP_DEBUG_LOG', true);

This will save the errors to a debug.log file inside the /wp-content/ directory. For more details on debugging WPML, visit https://wpml.org/documentation/support/debugging-wpml/.
If after enabling detailed logging you still do not see any errors, the issue might be related to .htaccess being overwritten by WPML settings for language directories. You can find more information and a potential workaround here: https://wpml.org/faq/why-is-htaccess-getting-overwritten-with-the-language-folder-on-my-wpml-website/.
Please ensure to back up your database before making any changes.

If this solution does not resolve your issue or seems irrelevant, 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 the problem persists, please open a new support ticket with us for further assistance.

saeedG-2	Background of the issue: I am trying to resolve an issue where all the links on the translated version of my site, hidden link, lead to error 500. The issue seems to be deeper than just menu links. Links work fine on the non-translated site. I am not seeing any PHP or WordPress errors in the debug logs. Both WPML and WordPress are updated. Symptoms: All links on the translated site result in error 500, but they work when accessed in a new tab. Questions: Why do all links on the translated site lead to error 500? Why do links work when accessed in a new tab but not in the same tab? What could be causing the error 500 on the translated site when there are no PHP or WordPress errors in the logs?

Andrey Supporter Languages: English (English ) Russian (Русский ) Timezone: Europe/Kyiv (GMT+02:00)	You emnitoiend aobut the debug log. Have you enabled it in the following way? To enable it, open your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to: define('WP_DEBUG', true); 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 ); The errors will be saved to a debug.log log file inside the /wp-content/directory. https://wpml.org/documentation/support/debugging-wpml/ If yes, and you still do not see any fatal error there. I suspect you might face the following problem: https://wpml.org/faq/why-is-htaccess-getting-overwritten-with-the-language-folder-on-my-wpml-website/ I would suggest testing the workaround. Please backup your database before making any changes.
