I recently updated my avatar on Gravatar. I know discourse caches these images so I decided to manually refresh the image but it’s not applied and now I only have placeholder 1px avatar.
What seems to happen:
When clicking refresh, a new image gets downloaded and avatar index gets increased, but my user still has same index in URL returned from server.
Example from my local instance:
My user’s avatar: /user_avatar/discuss.tano.si/tadej/90/2_1.png
When I inspect Gravatar in user settings: /user_avatar/discuss.tano.si/tadej/90/17_1.png
I experience the same here on meta and on my instance (latest beta).
