After updating my Facebook App to enable Use Strict Mode for Redirect URIs the login seems to be working without issue but on logout I get an error message regarding app domains. I've made sure the domain is in the App Domains but it still isn't working. Does anyone have an idea how to resolve this?
you need to leave the field "App Domains" empty.
In the Facebook settings in your OneAll account you can find instructions on how to enable the strict mode.
