Sitemap plugin not working
Google sent several emails stating that Googlebot cannot access sitemap of forum.
I have "Sitemaps 1.2.1" plugin already installed on forum and when I click on the dashboard http://websitehere/sitemapindex.xml go the error message below
XML Parsing Error: XML or text declaration not at start of entity
Line Number 1, Column 2: <?xml version="1.0" encoding="UTF-8"?>
Do any person know reason for this and how to correct it?
