Google XML Sitemap SEO in General Add-Ons Support Posted November 5, 2009 I'm still getting the below error. I try replacing the XML with blank files. I try checking the sitemap.class.php but both solution did not resolve this problem. the admin/configuration has disappeared when this error occur. The only way to get it back is to run the SQL comment again. The Admin link will reappear but show a duplicate of everything. I initially ran the script as Alternate with diagnostic output, thats where i was getting the errors you were. However, once i changed to Standard and generated the file i had no problems!
