Error loading stylesheet (sitemap)

[1burtonrobert2]

1. Configured sitemap according to directions using "store/sitemap" location.

2. Changed sitemap url to the one I want since it was having errors no matter what location I used.

3. Sitemap should now be found at: http://anniversarygiftsshop.com/sitemap

4. Receiving error message using firefox:

"Error loading stylesheet: A network error occurred loading an XSLT stylesheet:http://anniversarygiftsshop.com/wp-content/plugins/datafeedr/sitemap.xsl"

5. tried it in explorer and it also did not work

6. FYI, in URL settings of factory I ran a test and the results come back that the urls are miss-matched, but that never used to happen.

7. store is working fine other than the sitemap and the erroneous url miss-match report.

Any help in getting the sitemap to work would be appreciated,

Robert
