I had fix it changing the inc\classes\DO_Common.php file.
Simply adding the variable $_allowHistorical on line 12
after var $columns = array();
now the code looks like:
class DO_Common extends DB_DataObject
{
var $_LoggingOff = false;
var $_ActiveSortFilter = array();
var $columns = array();
var $_allowHistorical = false;
...
now the Historical data support is disabled and I can
check/uncheck and modify data without problems.
