Some Bugs on XML Sitemaps
“XML Parsing Error Not Well Formed”
Here is one of the problem that I had for a long time but , just now noticed it. The sitemap.xml file failed to load , with the above given error description. The reason for this turned out to be my .htaccess file. There were few privileges that conflicted with the Google Sitemap Plugin, Removing these lines, fixed the XML problem.
