Add Page Tab dialog not working [closed]

Question

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.

Answer 1

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.
