Sort broken

Hello,

I have a table with 4 fields of 2 different types I am trying to sort.
There are 3 dates with the format DD/MM/YYYY and the other a check box.

I get an error on table initialisation: Uncaught TypeError: Cannot call method 'fnSetData' of undefined - jquery.dataTables.min.js:29

This is the page where the table is malfunctioning (debug code 'oleguy'):

Any help would be greatly appreciated.
