Add Page Tab dialog not working
facebook, tabs
Solution
It seems that Facebook has made another change and has not informed anyone. Below is a new link that appears to work. Just replace APP-ID with your application ID.
https://www.facebook.com/add.php?api_key={APP-ID}&pages=1
Problem
I was always using the direct Add to Page Tab URL like this: http://www.facebook.com/dialog/pagetab?app_id=238557109577754&redirect_uri=http://www.facebook.com And today that URL gives me "Sorry, something went wrong.". Did something changed on Facebook side? Or is it a temporary bug? Note that I have tried other redirect_uri params, such as the URL of the location where the app is hosted. It does always result in the same error. Edit: It's a bug: https://developers.facebook.com/bugs/304168516342380 You can use Graph API Explorer to add your page tab over API as a workaround. See the link above for details.
