Install appears good except when attempting to access admin page. I'm receiving a "page not found" error.

Also of interest is the URL address appearing in my browser:
"https://venturen.startlogic.com/SafeAir%201https://www.venturenetdesigns.com/SafeAir%201/admin/login.php?zenAdminID=283525204bc2818523687266d26a9e6e".

Any ideas as to why the address is duplicating itself? Thanks in advance -
