I have found what I think is the last problem to the recent upgrade... our MYSQL database version is too old and the PHP scripting language generator is too old... (sort of sounds like most of us, huh?)
I have just submitted a request to our host company to install the newest versions of both of these... It may occur within the next couple of hours. I stayed up late to find the problem and get it fixed while we have the least traffic on line.
Hopefully when I awake tomorrow...er, later this morning, we'll have the newer versions and all of our code problems will have gone away!!
Nighty night.
