what are these sitemap errors

[jcgoldy]

Warning: file(/home/kimballo/public_html/generator/data/sitemap.xml) [function.file]: failed to open stream: No such file or directory in /home/kimballo/public_html/generator/pages/class.utils.inc.php(2) : eval()'d code on line 32

Warning: implode() [function.implode]: Bad arguments. in /home/kimballo/public_html/generator/pages/class.utils.inc.php(2) : eval()'d code on line 32

It will not create a sitemap.xml.  But it did create a html sitemap?

It says it created the sitemap.xml but I get a 404 error when I try to look at it.

Hello,

make sure that:
1. you have "sitemap file path" pointing to your domain root in configuration (not to the data/ folder)
2. you have created empty sitemap.xml file in domain root and set 0666 permissions to it.
