On accessing the following URL I am thrown a 404 error with no other errors in the error log file or on the screen. This only seems to happen when I have an https protocol. If I turn off SSL I am able to view the configuration. This could be because I don't have a valid certificate but I would hope this module would still load otherwise I can't test on my local machine. I'm afraid to put this on my live site since signed in users are required to use SSL and checkout may fail to load the module.
I'm running Magento community 1.8.0.0.
