"Manage Events" Issue

I have installed version 3.4.3 and I can access every option in the component except "Manage Events". Every time I select that option I get prompted for a username and password. If I enter credentials, I just keep getting re-asked. If I cancel, I get a 401 - Unauthorized error message.

I have this module installed on other sites and this has never happened.

Does anybody have an idea what might be causing this?
