Background of the issue:
I am trying to load the advanced editor to keep editing content. It was working fine but suddenly stopped working. When I am in the Translations section and click on a translation, either in progress or not yet started, it starts to load but never gets beyond the initial load screen. (See screenshot.)
Symptoms:
No content actually loads. I have tried in both Chrome and Edge and have the same result.
Questions:
Why is the advanced editor not loading in the Translations section?
Is there a known issue with the advanced editor in WPML?
Are there any specific browser settings or configurations required for the advanced editor to work?
This randomly fixed itself. I stopped using it for the day, tried again the next day, and everything worked fine. I'd rebooted my computer since then, so it was likely clearing the browser cache that did it.
