do you mean my own facebook app settings? Those would be kind of dangerous to post on a public forum right?
You can hide all personal info like email, app ID and secret. Or you can just send me a PM with screenshots.
So I tried the Ucoz app instead. But it gave the same error. So it must be something else correct?
What's the uCoz domain of your website? .ucoz.com? There is an error with the .ucoz.com domain and Facebook, so the uCoz app won't work. But your own app should.
