I know this has nothing to do with your plugin specifically, but I'm not finding any useful information within facebook so I figured this could be worth a shot.
When I go to the developers apps page and enter my app name I get an error: "App creation failed
Your account must be verified before you can take this action. Please verify your account by adding your mobile phone or credit card."
I've verified my mobile phone number but I keep getting it. I can't get past this part. Any ideas?
