Ah that looks like it’s probably it. I’ll last you know for sure after I do the next update. I was waiting for things to settle down a bit with some of the work currently going on (featured links, groups, ember), but I will update things soon.
UPDATE confirmed this is fixed in the latest version.
I’m seeing this behavior again both on my installation of Discourse and on this installation. I updated my Gravatar quite a while ago and have clicked the refresh button with no luck. I am running 1.8.0.beta8
EDIT Scratch that, it seems to be updating fine on this installation. I’ll have to poke at my own install.
Just installed v2.5.0.beta2 and experience the same issue: after user creation it shows gravatar image, but can’t update it after image change on gravatar side. I see nothing in the /var/discourse/shared/standalone/log/rails/production.log pressing image reload in the user interface.
I can repro! The gravatar fails to update after I change it on https://en.gravatar.com/emails and select the refresh button on the Discourse user profile.
