I'm still having a problem
You may need to clear your browser cache. Instructions on how to do that in all major browsers are here: Selectively clearing site data and cookies
You should also clear cache:
- If you can sign in ok, but then see an error saying your user profile could be retrieved
- If the map does not appear but instead says "Waiting for map configuration" after sign in
Also, if you like, you can check if locally cached data is the problem by opening a Private or Incognito window and loading the site there - if it loads OK in a private window, but not in a regular window, that's a sign that the cached data is bad.
