I have the same problem... can someone help me out please? I am uploading it, but the images are broken...
If I check it in firebug, it shows this: data/avatars/m/0/11.jpg?1391988032
If I hover it, it says the image cannot be found. Looks like a path issue, but how can I solve that? I mean, what am I doing wrong? The permissons are all set to 777.
