[Resolved] Automatic Translation Interface Not Loading After Site Migration

Background of the issue:
Hello,

Since migrating my site from dev.sherpas.lu to boards.lu, the automatic translation interface (WPML Translate Editor) no longer appears when I click on the gear icon in my posts. The page refreshes, but the interface does not load. Instead, the URL changes to something like: edit.php?lang=en&referer=ate&ate_job_id=xxxxxxx.

Here are the solutions I've already tried:

Updated the WPML license key and domain on WPML.org.
Uninstalled and reinstalled the WPML plugin.
Verified the WPML Translate Editor option is selected as the translation method in the post settings.
Checked browser console for JavaScript errors (none found).
Cleared cache and cookies from the browser.
Could you please assist me in resolving this issue?

Best regards,
