I am trying to get facebook open graph action to work, however, the object debugger tells me it is getting response code 500 from the pages I want to use. When I try to paste the URL into Facebook to share, sometimes it says runtime error and sometimes it works, sometimes it just gets part of the image.
For example: http://www.literrater.com/book/10 This fails the debugger entirely with a 500 code https://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fwww.literrater.com%2Fbook%2F10
That same URL works when posting a status, sometimes.
Any suggestions about what I can do to fix this or at least diagnose the problem?
Edit: The site is hosted on windows azure as an asp.net web site. The blog at http://literrater.com/blog is php and the OG debugger seems to like it just fine.
