Login Goes To Wrong Page

Recently we moved the http://greenvillehigh1966.com Web site to a new server. In the process of the move something has changed when users login. Now when a user logs in, instead of staying on the Joomla main page with the User menu displayed below the main menu as normal, the user is taken to the SMF form main page.

How to I adjust Joomla so that after logging in on the main page, the user stays on the main page as is the normal behavior with Joomla?

This is what we are currently running:
Domain: http://greenvillehigh1966.com
Joomla Version: 1.0.12 Stable
SMF Forum: 1.1.14
JoomlaHacks JSMF Bridge: 2.0

We have setup a test user so you can witness the behavior. This account with be deactivated in a few days for security reasons.

Username = TestAccount
Password = testing

Thank you in advance for your help.
