I switched the path to my XF data directory (swapped CDN domain names). On the site itself the media gallery thumbnails etc are all fine, using the new URL. But my xml sitemap, despite the change happening over a year ago, still has old media gallery URL's in it using the old cdn domain. So Google is giving me 24k errors in my sitemap which I find annoying . I've rebuilt everything, but no matter what I do the sitemap still contains these out-dated URL's. Any tips on how to get the sitemap to start fresh?
