[Plugin: Google XML Sitemaps] Google sitemap generator currupts wordpress feed!

Since I installed this plugin I get this error in my wordpress feed.

XML parsing failed: syntax error (Line: 273, Character: 27)

It says the above error when viewing feed in Opera. In Internet explorer it says “This feed contains code errors.“

Feed seems to work fine in Firefox though. Any ideas on why google sitemap generator causes these errors? Any way to fix it?

I really like this plugin and don’t want to have to uninstall it so if anyone can help I’d appreciate it. Thanks
