That's not new. It has to do with the SSL cert; being issued for
www.ninjette.org, and quirks in forwarding from domain to domain.
If you go to
http://ninja250forum.com , it will jump to
http://www.ninja250forum.com, then
https://www.ninjette.org, and the cert will show up properly. The only time it shows the mismatch cert error is if someone goes first to a https:// site without the leading www: like
https://ninja250forum.com
Google is supposed to show everything with the leading www, so I need to make sure that happens for the ninja250forum.com domain as well.
EDIT: updated the prefs for that domain with google; its search results should show up with the leading www going forward (might take a day or two to cycle through)
