Facebook API Error: This IP can't make requests for that application.

If you're seeing a completely blank white page where your site should show inside the Facebook Page Tab or Canvas areas, please set the "Display Errors" setting in the Joomla -> Global Configuration area to "Maximum". Then the white page should show an actual PHP error message as to what's happening. Let us know that message.

Beyond that, whenever we go to your Page or Canvas we can see your site. If you're seeing something else and the above doesn't help, please post a picture of what you see.

Thanks,
Alex
