Please don't get me wrong but this forum don't seem to be
the right place for you have a problem with the facebook api.

I would have a look at the facebook developers pages to solve
this problem.

Here just one link I found with the help of our friend google:
http://forum.developers.facebook.com/vie...pid=189253

Hope you find a solution soon.

There are lots of pages talking about that problem - just have a look:
some google results for your error message
