I have a tab app on a Facebook page that works only for SOME users. I am not sure what the distinction is because one of these users is an admin. SSL is working fine and its not in sandbox mode. Is there any reason why it would show a blank page for some people?
Here is the URL https://www.facebook.com/pages/Purple-Haze-l-Warehouse-Rave-Series/414833951888732?sk=app_263980683718092
SSL is working fine
Yes, but the none-SSL version isn’t.
https://exterbox.com/dev/ravetv/ is the URL for your SSL version of your app – so I guess http://exterbox.com/dev/ravetv/ is supposed to be the non-SSL version, but calling that just gives a 404 Not Found error.
