ACS and facebook login & # 8594; display = touch broken?

Question

I use ACS to log in with Facebook. Until this week, I could add display = touch at the end of the URL that ACS provides. Now, when I do this, I get an “Internal HTTP 500 Server Error”.

Any ideas? The url looks something like this:

https://www.facebook.com/dialog/oauth?client_id=myid&redirect_uri=myreturnurl&scope=email&display=touch

I tried m.facebook.com with the same result.

Again, this worked earlier ... and if I remove display = touch (or change it to display = popup), everything will be fine.

I want this to appear in a WP7 application, so touch :)

Thanks SR

Update: the docs say "Display mode in which the dialog box is displayed. There may be a page, a popup, iframe, touch or wap." Touch and wap return "Internal HTTP 500 server error."

Also crashes my app and even Seesmic. It must be installed FB. I created an error report here: https://developers.facebook.com/bugs/287213021307964

Answer 2

I ran into this problem a few days ago. It seems that the changes have occurred on Facebook, despite the fact that their documents say.

I tried using display = popup instead, which worked for me.
