Sitemap Generator Forum

When I attempt to create a sitemap, I receive this sitemap which refers to [ External links are visible to forum administrators only ].
The robots.txt file doesn't disallow anything.
Can anyone please assist? If I use the free sitemap generator, a site map is created but not in Pro. Thanks.

Hello,

looks like your website redirects requests from generator bot to "refused.htm" page. Could you please check that your server/site doesn't block requests from our IPs:
