Reported via email:

First of all, there is a bug in the Facebook App ID sanitization:
By casting the entered App ID as Integer you are limiting the App ID to numbers below >2147483647+1 (maximum Int value on 32bit systems). That results in every App ID > >2147483647 being saved as 2147483647 and therefore Facebook Connect will fail.

The following needs to be done:

  1. The app id as seen in the markup needs quote wrapped around it. Without quotes when you enter a app id that has letters and numbers you'll see a JS error.
  2. The facebook sanitize needs to allow for numbers and letters only. You can probably just use the WordPress function esc_attr
