Gravatar images doesn't update


Changed my Gravatar like 1 week ago, but it doesn’t update. Tried everything:

  1. Hitting the update button for Gravatar
  2. Changing to no profile picture, wait for a few days and add it back
  3. Remove browser cache and do above
  4. Add the profile pic by uploading it manually, but it won’t let me.

Seems like a caching issue as my old profile pic is added back, or that this forum doesn’t sync correctly with Gravatar. It works everywhere else.
