I used JomSocial Facebook Connect before but now installed JFBConnect6 mainly because it's invite fb friends feature. JomSocial FB Connect worked without any problems. I installed and activated JFBConnect according to the step by step instructions.
But when I now:
Click the JFBConnect button at JomSocial frontpage (IE8), I login to facebook in the popup. The popup dissapears but nothing happens. When I browse to /jomsocial/profile/ it seems like the page is refreshing in a loop several times. When I go back to home I see error results: "Automatically logging you in with your Facebook credentials" (43 times)
Error "Username and password do not match or you do not have an account yet." (42 times).
After installing JFBConnect I didn't immediately import FB profiles from JomSocial Connect but tried login with this account before I imported them. When I finally imported the JomSocial profiles I saw this account profile already in the list. Don't know if this had something to do with this problem but I thought I should mention.
Another thing, I see the logout link but I don't seem to be logged in as when I change something in the edit profile the system says I don't have correct credentials. But the changes I made in edit profile where actually implemented... Hmmm, weird.??....
I have deleted the API key etc from JomSocial Connect
I also attach the order of user plugins:
Settings:
Enable Returning User Redirection: YES
Returning User Redirection: Profile
Auto Login Facebook Users: YES
Log Out Of Joomla Only: NO
Enable Logout Redirection: YES
Logout Redirection: Joomla! Home
Display API Errors On Front-End is now also set to YES
