[Plugin: Simple Twitter Connect] Login Issue

When I log out of my WordPress installation to test the login functionality of this plugin, the following happens:

1. I log out.
2. After the wp-login.php page loads asking for my credentials (with a Login w/ Twitter badge at the bottom), I press the badge.
3. I am taken back to my websites homepage. I notice the URL has been appended with a command which I assume should open a login screen.
4. I am still waiting for something Twitter related to happen, allowing me to login using Twitter.

This is what my URL looks like after I press the button to login with Twitter:

http://www.ngbcstudents.com/?stc_oauth_start=1&stcaction=login&loc=http://www.ngbcstudents.com/wp-login.php?loggedout=true

I have tried using the plugin both with Safari and Firefox. The initial setup was followed to the T, and was successful. However, nothing seems to be happening.
