Hello Nick,
So sorry for the delay in getting back to you. Please check your Facebook app and make sure the "App Domain" and "Website URL" have the correct information.
App Domain -> blatantlyblunt.com
Website URL ->
http://www.blatantlyblunt.com
If this does not help please send us your Facebook login and we will have to take a look at the app and do some tests
Hope this helps.
Thanks!
