Sitemap Generator Forum

Please help!
Do not quite understand what happened. My site works now on Opencart platform, but Unlimited PHP Sitemap Generator doesn't work at all. Please see the screenshot.
What am I to do?

Hello,

probably there is a configuration problem - it looks like your server doesn't allow local network connections via port 80 (http) or 443 (https) - as a result sitemap generator is not able to crawl the site. This is usually related to firewall installed at the host - could you please contact your hosting support regarding this?

I'll try, thank you!
