[plugin:FeedWordPress] facebook feed error

I’m using Feedwordpress to link a facebook page feed to my word press site. Every page I’ve tried to add using the syndicated site adder comes back with an error. The url I’m using is:
https://www.facebook.com/feeds/page.php?format=rss20&id=

tried this format with a few page ids and they all come back with an error.

This XML document is invalid, likely due to invalid characters. XML error: EntityRef: expecting ‘;’ at line 11, column 568

Am I using the correct url?
