Suppliers on site map returns a 404

[Rich I]

I have set up the site map module and the site map link is in the footer. When I open the site map and click on suppliers I get a 404 - Page not available.

I have unchecked the supplier box on the sitemap module but that has made no difference.

I have suppliers listed and tied to products, but again no change.

Has anyone else had this issue?

Fixed - I had not enabled "Display suppliers and manufacturers" in the general preferences in the BO
