Everything is working now that I uploaded it to a production server.

I also had problems with link analyzer showing false positives for K2 categories, those are now corrected.

I had it in a local VM for development. Changing the hosts file of desktop to point to the VM. The DNS record, for the domain, stayed the same -- pointing to the old location on the production server with an old version of the site without JSitemap. I'm guessing that was the cause of the problem, somehow. AFAIK, the VM is properly config'd.

Thanks for offer of help. But it's resolved now.
