CORS error on loading the interface - stuck on loading screen


Recently (last month) occasionally I get errors when loading interface - most prevalent is this:
Access to Script at ‘https_edited_dueto_new_user://’ from origin ‘https_edited_dueto_new_user://’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘https_edited_dueto_new_user://’ is therefore not allowed access.

and when that happens, i am stuck on the loading screen.
What i have tried (without success)

  • reloading page
  • force reload
  • clearing cache and reload
  • clearing cookies, reload and re-login
  • ?reset=1

Just happened half an hour ago and now it works again…


It still happens … fortunately now a simple reload is sufficient to remedy, but it is annoying…
