Hi Bob,
i can't guess what's wrong but i can try.
1. Ensure that the plugin 'System Jsitemap utilities' is published
2. Ensure that domains used for metainfo is the same used to open and check pages. If you specify metainfo for
http://www.atlantainternetdesign.com/ and open
http://atlantainternetdesign.com/ without www prefix they won't apply, it's a different link
PS: your site
http://www.atlantainternetdesign.com/ takes ages to open and shows badly at our end. Maybe it's important to let you know.
Cheers,
John
