I got my problem solved. What I had to do was change the .htaccess file.
There is a special line in the default .htaccess for people that use 1and1 hosting.
I changed it from
AddType x-mapp-php5 .php
AddHandler x-mapp-php5 .php
Now Admin Login and Customer Login works great.
Funny thing though that the way I had it was per 1and1’s FAQ’s and also from what I had read in these forums.
Roy, you might want to change that line for people using SSL with 1and1 hosting in the .htaccess file.
Thanks to anyone that took the time to look into it.
