I don't know what happened, but I can't show my uploaded avatars, even if they are uploaded and on the server... They are showing broken...
For example, I see this for a particular user: data/avatars/m/0/11.jpg?1391988477
If I hover it, it says that the image can not be found. I checked it on the server and there, it is saved as 1.jpg, not as 11.jpg. So if I change this number in Firebug, it shows me the avatar! The problem is: how can it be that this number is being changed? How can I solve this?
Do I have to import all the data once again to solve it?
