I'm still receiving the DataTables error above, even on browser that never access that page before (so there are no stored cookies etc). Happens in FF, IE, and Chrome:
DataTables warning: table id=pools-table-details - Requested unknown parameter '5' for row 0. For more information about this error, please see http://datatables.net/tn/4
