404 Error - WPML

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

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.

If this solution does not resolve the issue or seems irrelevant due to being outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent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 the problem persists, please open a new support ticket for further assistance.

keremO-2	Background of the issue: I am trying to open pages in English from my website. When I'm at the home page, I click the English button, and it opens without a problem. However, when I click another page, it sometimes gives a 404 error. The page works in both Turkish and English versions. If I go to that page in Turkish mode, it opens, and then I click the English button, it opens again. The issue can be seen at: hidden link Symptoms: I sometimes get a 404 error when trying to open English pages from my website. Questions: Why do I get a 404 error when trying to open English pages? How can I ensure the English pages open without errors?
