This thread is resolved. Here is a description of the problem and solution.
Problem:
You are trying to use the WPML plugin to translate content, but the translator is not opening at all. It remains stuck and does not load the content. The error log shows a status of 503, indicating a server-side issue.
Solution:
We recommend that you test the translator again to see if the issue has been resolved. It is possible that the problem, which was related to a server error, has already been fixed.
If the problem persists, it might be due to an outdated solution or a different issue not covered here. 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 none of these steps resolve the issue, please open a new support ticket at WPML support forum for further assistance.
