XML Sitemap content (0 pages) - No pages indexed

[simplemind]

Hi,
The free sitemap generator does not index any pages. It runs the generator successfully and shows message "XML Sitemap content (0 pages)".

Another sitemap generator (from a different website) worked fine but I like this generator much more and would like to know what is the issue I have.

The website I am running the sitemap generator on is [ External links are visible to forum administrators only ]
I do not have a meta tag with robots nofollow and my robots.txt disallows multimedia bots only. I did try deleting the robots.txt file and running the generator though, but without any success anyway.

Also, this sitemap generator used to work fine on the same website earlier but not anymore.

Any ideas, please?
