Can't reset sitemap URL

Hi Guys,

I'm having a minor issue with the WPMU DEV SEO plug-in.

I recently migrated my site from http://test.fundsport.com to http://www.fundsport.com. Whilst the migration went relatively smoothly, my sitemap URL is still 'test.fundsport.com/sitemap.xml'.

I have tried de-activating and re-activating the plug-in as well as turning the sitemap section of the plug-in on and off but the URL is still sitting on the test server.

Any ideas?
