Permissions Not Working Correctly?!

I am working on the latest version of WP MultiSite & BP. I purchased the plug and installed it to my test site, created the FB app and all worked fine. I now duplicated that site over to a .com, created a new FB app for that site and the login is spitting back the following error message:

Given URL is not allowed by the Application configuration.: One or more of the given URLs is not allowed by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains.

've double checked the FB setting and they are pointing to the new .com I check the Permission Token panel and all it's doing is whirling the loading bars. When I click refresh user access token, I get the same error message above!
