I just get a spinner when I try to load the editor in Pro.
Have tried with the current versions of Chrome and Safari and have tried all the options in the common issues post:
-checked for plugin conflict by deactivating all plugins
-increased PHP memory
-updated PHP version
-deleted and reinstalled PRO
-etc No joy.
I had this issue a few months back and it resolved itself the following day, but it’s back.
