My ZenCart is versioin 1.3.8a and have sitemap version 1.3.19.

I am seeing alerts within my Google Webmaster tools for both my ZenCart categories and products XML's. They read....


"URLs unreachable
When we tested a sample of the URLs from your Sitemap, we found that some of the URLs were unreachable. Please check your webserver for possible misconfiguration, as these errors may be caused by a server error (such as a 5xx error) or a network error between Googlebot and your server. All reachable URLs will still be submitted".

"Details" show a 500 type error. I checked under Google Webmaster/Site Owners Help, but not seeing anything related to my alert/error there.

The only thing I thought might help was to hit the "resumbit" sitemap.

That did not work....

Also... hate to confuse the issue... But...

The ZenCart is a subdomain to my .com . Everything looks perfect within Google Webmaster tools for that .com sitemap.

Although I wonder if there is an issue connected somehow.. A site called Ganoksin is no longer able to auto add to that sites blog from my .com blog like they use too... They say it is a sitemap problem.

Is it possible that if the subdomain is having XML issues that it would effect the root site ?
