I have created a new Facebook app. Whenever I visit the canvas page (https://apps.fac...) I get redirected to the Facebook 4oh4 page.
The canvas URL is set to: https://mgnewmedia.com/brandgame/
Which you will see is as basic as it could possibly be, yet I still get a 404.
I have used the debug tool, which does read it fine. I have checked the URL on other Internet connections and on other Facebook accounts, all 404. The app's canvas page is: https://apps.facebook.com/brandgame/
I have deleted the app and re-added it with no luck. I have also tried putting sample apps in place incase it's 404'ing due to no SDK being present, but that's not the case either.
I have a full, valid SSL certificate in place on the hosting, as you can see. I run several apps on here already with no such issues.
