I guess the second time is the charm...
I normally do use a custom template set, but I had switched over to the default template prior to installing the first time. I just tried exactly the same thing and now it works...go figure. Leave it to me to screw up what should be a relatively easy install. LOL
I made the necessary modifications to the custom template and the site now appears to be running fine with the autologin.
Thanks for your help and all the great things you do for the community!
