I didn't seem to get the developer request, but I think I can see the problem already. In the JFBConnect Overview area is the following error when I visit the page
bravozulunetwork.com (no www)
Connect URL:
www.bravozulunetwork.com/
WARNING: POSSIBLE MISCONFIGURATION
We suggest updating your Connect URL to:
bravozulunetwork.com/
You can do this by visiting: Facebook Developers
Select your application->Edit Settings->Connect URL in the Connect section.
In your Facebook application, can you go to Edit Settings and then the Web Site tab. Change the settings to the following:
Site URL:
bravozulunetwork.com/
Base URL: bravozulunetwork.com
The error you're getting is likely because your Site URL currently uses www, but visitors can come to the site without the www. By setting the Base URL, this will let Facebook know that any subdomain is suitable to use for your application (www or non-www).
After this is configured, you shouldn't get the error anymore. As for the Invite issue, when I log in (with the www address for now), I'm properly seeing the module. What are (or aren't) you seeing?
