I am currently on v1.8.0.beta4 +283. I just upgraded to beta from stable. The problem I am reporting here was happening also on stable v 1.7.2. I upgraded to the beta channel hoping for a fix, but it’s the same. It was not happening on stable prior to 1.7.
Since the stable upgrade from 1.6.x to 1.7.0, and now also on v1.8 beta, I am seeing random blank avatars in our forum. When I look at the users that are affected, I see that in the preferences for that user, the profile picture setting has been changed to “Custom picture” but there is no custom picture and so the avatar is either completely blank or appears as the generic avatar. When I checked with users for whom I am seeing this, they are NOT manually setting the preference to “Custom picture.” It is somehow happening “by itself” behind the scenes.
We are using WordPress SSO via the wp-discourse plugin (to which I am a code contributor), but I do not have the override avatar from SSO payload setting turned on.
Here is what my “avatar” related settings look like:
