This is weird. I created a Facebook iFrame App that worked fine in every browser I’ve tested it on. Then Mountain Lion came out. For some reason macs running the new OS and Safari 6 can’t see the app. The Facebook chrome is there, but the website isn’t loading. (The app is just a website hosted elsewhere). I have another mac running lion that has Safari 6, but it works fine. So it has to be Mountain Lion that’s causing this problem. I don’t see how the operation system would affect this, but it seems to be.
Any suggestions?
No matter what browser I am using, the address https://www.yellow-mountain.com/latest_picture/ is not reachable (my browsers try to connect to the HTTPS version because I am browsing FB over HTTPS). And even outside any iframes I can not connect to that address.
Reaching it just via HTTP works fine though.
So talk to your server admin about getting SSL to work for your server/domain.
