[Closed] Advanced Translation Editor is slow or not working. Error logs show a great amount of entries.

The WPML Advanced Translation Editor is showing a very large number of repeated errors. The logs constantly report an “Api error missing resource” followed by “No sitekey found for this website.” This makes it look like the ATE cannot detect or validate my site key, even though the key appears correct and active in my WPML.org account.
These errors are slowing down the workflow and, at times, preventing the ATE from loading properly.
Because the site key seems valid but the system keeps reporting that no site key was found, I’m unsure whether the registration is actually working.
