Google XML Sitemap SEO in General Add-Ons Support Posted August 19, 2010 It sounds like you may have missed one of the files when uploading. You may also want to search back through this thread for that problem since I think it has been addressed before. Jack, I've searched through. The previous post (#350) was because the gss file for forgotten. Other posts #53,75,83 didn't help too as all my xml files has the same error message. I've also tried replacing all the xml files and set the permissions correctly without success. All my files are in place and permissions given correctly to all xml files. What else do you think I've missed?
