System Settings page redirects to a 404 Page

After I enter the System settings (upon initial setup) it redirects to a 404 Page not found.

Here is the page after redirection:

Note that the "/action" directory is actually "/actions" on my server. I tried again by renaming "actions" to "action" on the server but still no sucess. Also note that the URL makes it look like the page to be redirected too is in an "/install" directory off "/systemsettings". When I looked at the "systemsettings" directory there is an install.php script file present but not an /install directory.

Unsure how to continue with the install.
