I have been using the standalone site map for months without any problems.
last week Google showed an error on the site map with the error message...
Network unreachable: robots.txt unreachable
We encountered an error while trying to access your Sitemap. Please ensure your Sitemap follows our guidelines and can be accessed at the location you provided and then resubmit.
I have re submitted 5 times with the same result....
The tools here on this site show a sitemap error as well...
XML Parsing Error: no element found
Location: [external links are visible to admins only]
Line Number 1, Column 1:
My sitemap is at [external links are visible to admins only]
My hosts enabled phpsuxec at about the same time I noticed this error occurring... They said that this was enabled to stop spam but I wonder if somehow the Googlebot is being blocked as well...
Could anyone help please?
