Michael,
Just got into your site. There were a few strange things I saw, some I could correct.. others I need more info on.
1) You had all the JFBConnect Profile plugins installed and enabled. Since you don't have Community Builder, JomSocial, Kunena, or K2 installed.. I disabled those.
2) When I enabled the "Search Engine Friendly URL", none of your main menu URL's worked. For instance, when I went to:
www.pokerbrands.ca/index.php/freepokermenu
I received an error "No input file specified."
Not sure what that is, but it may be an indicator of other issues on your site/server related to SEF URLs.
How are you enabling SEF URLs, and do they work normally for you?
3) On the JFBConnect Overview page, the "Domain URL" for your Facebook application isn't specified. You should set the "App Domain:" setting in your Facebook Application to:
pokerbrands.ca
4) You don't look to have sh404SEF installed, which is a 3rd party SEF extension. However, in your plugins manager, you have the "sh404sef - Sample component support plugin" installed. It's not enabled, so it's not directly causing issues, but if sh404SEF was installed, and not fully/properly uninstalled, that could easily be what's causing problems now.
Hope that gets you started on things to look into. Really not sure what state the site's in, but a lot of this doesn't look to be directly related to JFBConnect, other than #1 above. We'll help diagnose and fix you up however we can though.
Thanks,
Alex
