Migrated site: plugin loading old site map

Hi,

I migrated a site to a new domain and when I try to view the sitemap on the new domain I get this error message:

Error loading stylesheet: An unknown error has occurred (805303f4)

http://www.abledragon.com/demo-site-3/wp-content/plugins/google-sitemap-generator/sitemap.xsl

That URL is the old site domain. I’ve tried uninstalling the plugin (and deleting all files) and re-installing it but the error still exists.

Where can I edit this URL? I only need to change the domain name but I don’t know where to find the correct place to edit it.

Many thanks,

Martin.
