Can I get a few hints on what I may have broke to cause these errors. I get them with the original release and the new release.

Good suggestion on the link, but. The issue is occurring on the upgrade also. I think I have narrowed down the fault to something in my old database. I find no problem with a fresh install and new database. I will report back when I find / resolve the difference.
