* Could you tell me how you have the profile import set up in JFBConnect > Profiles area? Are there any fields mapped? Which profile extension are you using?
* What version of Graph API is your application set to use?
If you'd be willing, it'd be quickest to diagnose this problem by putting a debugging statement in the code to see what's coming back from Facebook. If you'd like me to do it, please send me a private message with FTP credentials.
Otherwise, you can add it yourself and tell me the resulting text that gets printed out when you perform the profile import.
In /components/com_jfbconnect/libraries/profile/facebook.php, at line 70, add the following line, so the code looks like this:
print_r($field);
if (strpos($field, "friends") !== false)
Additionally, these are just warnings. You can set the "Error Reporting" setting in the Joomla Global Configuration to None and they won't be printed out. That's just a notification message and those should be hidden on any live site.
