I have a situation where I need to be able to make calls to my Facebook App from 2 domains. Previously everything has come from www.domain1.co.uk but now I need to change my Website platform url to www.domain2.co.uk.
In accordance with this qu and answer (Facebook login with multiple domains.) I have added a dummy canvas page (no page tab tho) which has been assigned to www.domain1.co.uk and changed my website platform url to be www.domain2.co.uk. I have then added www.domain2.co.uk to my App Domains.
So my App Domains are now www.domain1.co.uk and www.domain2.co.uk.
Currently the Facebook Login function still works for my website @ www.domain1.co.uk but not @ www.domain2.co.uk. I made the changes a good 5 hours ago.
I use Login with Facebook and Register with Facebook via this app. Client OAuth Login and Web OAuth Login are enabled for this app. There are no Valid OAuth redirect URIs stored.
Could anyone point me in the direction of what I need to fix here please? Many thanks. Kind Regards Liz
Okay intensive investigation has revealed that it helps to make the changes to the correct app. The changes kicked in immediately at that point. Apologies for any wasted time.
