I noticed I am getting crawl errors in Google Webmaster tools, and found that the WordPress SEO sitemaps are not working properly:
http://www.ianstuart-bride.com/sitemap_index.xml
http://www.ianstuart-london.com/sitemap_index.xml
http://accessories.ianstuart-bride.com/sitemap_index.xml
http://accessories.ianstuart-london.com/sitemap_index.xml (not currently accessible)
This error message shows when viewed in Firefox:
XML Parsing Error: not well-formed
Location: http://www.ianstuart-bride.com/main-sitemap.xsl
Line Number 1, Column 699:
W3 Total Cache, to see if that was the culprit, but it isn't.
What's going on?
Thanks
