Hello there!
I have this issue now that whenever I log in using JFBC, I get this error:
The avatar file (/tmp/jfbc_650063770pic_tmp.jpg) for user 1114 does not exist. Using default image instead.
The avatar for the profile is not shown anymore. Furthermore, when I check the tmp folder, the file is there. I suspect it is also jomsocial related since when I try to upload a new avatar using jomsocial, it works but the thumbnails are not created for the avatar.
It happened after I was trying something in my local joomla host and I did not realize that the local joomla has its ftp setup to the live site. My config.php for the live site was a mess that I had to edit it and put in the proper values to make the site live again (database, username, passwords,etc.).
I've been using JFBConnect for the longest time now and I'm really happy about it. I hope mess could be fixed. Thanks!
