Hi John,
Problem is not upgrade opf extension. Problem started before upgrade. I thought upgrade might fix. We are using no 3rd party SEF extensions of any sort. No Sh404sef on this site. This is not the site you worked on before.

Thank you for reply. Always fast support here!

Hi,
i exclude that the issue is due to the upgrade to JSitemap 4.2, most probably it was already present before.
Try to check if you have a third party extension that manage URL rewriting such as sh404sef or similar, i guess you have a problem with such a thing.
I already worked on your website http://www.crystalwind.ca/ in the past.
