Avatar not getting imported

Hallo there,
We just went live with the jfbconnect on our site at www.sintagespareas.gr

All seems to be working as it should, with one exception: when someone logs in via facebook, their avatar is not getting imported.
We tried both for existing accounts and new accounts.

We think we have everything set up exactly as they were in our dev site, where we didnt have this problem. Any ideas that could point us to the right direction into solving that?

Alex, if need be I can give you admin access in to the live site via pm.

Be well,
Konstantinos

Edit: the problem seemed to be the permissions in the directory where the avatars were saved. With the upgrade of CB they had changed and the system could not save avatars. Fixed it.
