Our apps are getting error 500 on this call :

https://www.facebook.com/dialog/oauth?client_id=89dc1edc0036d868930ccbac657e8b7f&redirect_uri=https%3A%2F%2Fapps.facebook.com%2Frealmofempires%2F&scope=email

Does anyone know of any issues?

There is a work around, just replace the "www.facebook.com" with "m.facebook.com"

Are you guessing the change happened at Facebook at 8:21 based on when you started getting the error, or is there a way to see when Facebook publishes API changes? – GrahamMc
Did you managed to fix this? I have this problem but the funny part is that it only does it for me in IE (all versions). Any idea how I can fix this? – Mihai Fratu

Facebook seems to have dropped support for the old API KEYs. If you look at your App Settings page, you'll see App Id/Api Key. These were merged back in 2011, so just replace your api_key with your app_id for the client_id parameter.

This should have been a breaking change.

I can reproduce your problem by removing all cookies at facebook.com and then visit your posted link.

If you visit http://www.facebook.com once, then your URL will work. If found it now needs a cookie at facebook.com to work (named datr at facebook.com). There must be a change/problem at facebook.

It also works if you visit the corresponding login.php directly.

Depending on what oauth tool you're using, it's possible to get an error 500 if the API key and/or secret are missing
