I'm a little confused. Above you said that you are "able to get some profile information from facebook". In the last post though, it sounds like the row in the jos_comprofiler table isn't being created at all? Something's strange there, can you explain a little more if the user's profile is being created at all in CB?
The only other things that I would suggest to check are:
1) Make sure in the CB profiles plugin for JFBConnect that the import avatar option is enabled.
2) Go to Help->System Info in the admin area, click on the "Directory Permissions" tab, and make sure the /tmp and /images directory are both writable. Additionally, the /images/comprofiler directory should be writable as well, but you may have to check that through FTP or on your server.
If none of those work, I don't have any other suggestions. Beyond this, we may need to request access to the admin area of Joomla to help diagnose and fix this further.
Thanks, and sorry for the troubles.
