I have a problem with my sitemap too. I don't understand how to fix what the error is. Can someone help...I am new to this.
Here is what it says:
Schema validating with XSV 3.1-1 of 2007/12/11 16:20:05
Schema validator crashed
The maintainers of XSV will be notified, you don't need to send mail about this unless you have extra information to provide. If there are Schema errors reported below, try correcting them and re-running the validation.
