Thanks for the info.
A few of the sites are...
http://www.Coffee-Authority.com
http://www.Handcrafted-Replicas.com
http://www.Trollbeads-USA.com
I'll check out the smarty logs to see if I can find anything.
As far as the HTML catalog goes, it still works just fine. I'd thought to leave it there for existing links from the search engines. It doesn't seem to be a problem and I was going to leave it alone until the engines switch over to the new links.
This bring to mind a new question... We've been using Google Site Maps and I have a script that generates the links based on the HTML catalog. Any idea how to use this with XC SEO?
Thanks,
Eric
