Problem: The client is experiencing an issue where the Advanced Translation Editor is blank after restoring their site and re-registering their site key. The error log indicates 'Api error missing resource: No sitekey found for this website'. Solution: We first verified that the Advanced Translation Editor is functioning correctly by attempting to translate pages, which did not show any issues. We then suggested that the client record a screen recording of the issue using Loom. Upon further investigation, it appears to be a browser-related issue. We recommended that the client disable any browser extensions or try using a different browser to see if the issue resolves.
If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix,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.
