Background of the issue:
We are experiencing 500 Internal Server Errors on translation pages /ru and /en. When WPML Multilingual CMS is active, the problem persists even when all other plugins are disabled. Disabling WPML Multilingual CMS stops the 500 error but results in a 404 error instead. We have tried updating permalinks, checking .htaccess configurations, and ensuring that WPML settings are correct, but the issue remains unresolved. We need assistance in identifying and fixing the root cause of these translation page errors. Link to a page where the issue can be seen: hidden link

Symptoms:
A 500 Internal Server Error on the translated pages (/ru, /en) when WPML Multilingual CMS is enabled. When WPML Multilingual CMS is disabled, the pages show a 404 error instead. This issue persists even when all other plugins are disabled.

Questions:
What could be causing the 500 Internal Server Errors on the translation pages?
Why do the pages show a 404 error when WPML Multilingual CMS is disabled?
Are there specific WPML settings that need to be adjusted to resolve this issue?
Could there be a conflict with the .htaccess configurations or permalinks?

Hello 🙂

To debug this issue further, I would need to check your site settings once, for this I would need temporary access (wp-admin and ftp) to your site.

So could you please provide me with those details, you will find the needed fields for this below the comment area when you log in to leave your next reply.
