Problem with fixed header

Hi,

First of all thanks for this great plugin! It really simplifies a lot.

Am having problems getting to set a fixed header row for my table. This is what I’ve done so far:

Installed the datatables fixedheader plugin
Removed all #rowspan# and #colspan# from table
Added datatables_fixedheader=”top” in shortcode
Re-enabled the “Use DataTables” checkbox

But it’s still not working. Is there something else I could be doing wrong? Here is a link to the page: http://famouslawnmowers.com
