Template list bullets

Hi
I just downloaded a template from templatemonster and I have a problem: I want to use a list with disc as list style type, but the discs won’t show, even if I use a class explicitly for that unordered list with the list-style-type set as “disc”. This is the url to my webpage:

Any help will be very appreciated.
