The FaceBook login is now not working either. Please advise...I ugently need to get this working.
Can you explain a lot more as to what's not working? I just tried, and it logged me in just fine. There were many, many PHP warning messages, like shown originally in your post. However, none of them looked to be coming from JFBConnect. I'd suggest setting Error Reporting to "None" in the Joomla Global Configuration area to suppress those.
For the logout issue, there's something wrong on your site that is unrelated to JFBConnect. Regardless of how I login (using the SCLogin module or 'normally' through the Joomla login), if I go to the *standard* Joomla logout URL below and try to logout, I can't logout there either:
vombudsman.com/index.php?option=com_users&view=login
There is a continuous redirection loop and Itemid=1 is being inserted in the URL as well.
Something in your configuration is performing extra redirections, and I'm not sure what it is. I'd recommend disabling SEF URLs and turning off caching to start with. I'm not sure what the actual cause is though.
I hope that helps. Until the 'standard' Joomla logout functionality works, I'm confident the SCLogin functionality won't work either. Of course, you can disable the SCLogin module and JFBCSystem plugins to see if that makes things work (eliminating them from your site), but I don't think they will have any effect.
Thanks,
Alex
