Is there a general error with the login redirect plugin?

The login redirect plugin has been installed and the destination page chosen under General in Settings. I'm using a sidebar login and tested the plugin while viewing the contact page. After login I should have been directed to the front page but this never happened.

I tried several combinations and deactivated all plugins exept the Shortcode Exec PHP plugin since this is the one that I used to create the sidebar login. However, it did not make any difference.
