Problem: The client experiences a 404 error when trying to open English pages on their multilingual website, although the pages exist in both Turkish and English. The error does not occur when switching from Turkish to English on the same page.
Solution:
After further investigation during a chat with the client, it was observed that there was a lot of custom code added in functions.php file which was causing this irregular behavior. Pages were throwing 404 randomly.
Since custom coding is out of scope of this forum, we advised the client to remove all the code and check piece by piece while keeping an eye on the issue.
