Working with Facebook Connect

I have two files with identical code (it is the code they mention here: http://developers.facebook.com/blog/post/198). I have one of these files here: http://gnucom.cc/test.html and another one of these files here: http://blog.gnucom.cc/test.html. I have the main URL set to gnucom.cc and the Connect URL set to http://blog.gnucom.cc.

For the life of me, I cannot figure out why the version accessed from the subdomain doesn't work. I receive a loadin开发者_C百科g icon and that is it - afterwards it disappears.

Can anyone suggest what I may be doing wrong?

You should type in http://gnucom.cc instead of http://www.gnucom.cc (if it's not already this way)
