An error occured: x_csize: 0

Could you please assist me with resolving an issue I'm encountering? I recently installed the latest version of the software on the server. However, I'm consistently receiving an error message stating "x_csize: 0." Despite attempting all the troubleshooting steps recommended in the forum, I've been unable to resolve the issue and get the software to function properly. Any guidance or assistance you could provide would be greatly appreciated

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?
