When inspecting your template page, the CSS wikia returned is: border-bottom: 1px none #ACB78D; So there's the problem. You can fix this by using border-bottom: 1px solid #ACB78D; and you can get rid of the border-bottom-color property.

It looks like the borders are suppressed in other parts of the style sheet, and the black border you were looking at was actually the upper-border of the cell below.
