I can't reorder fields anymore

Hello,
I’ive updated to 4.14 version and I can’t re-roder the fields.
Here below there is the console log:

`TypeError: ‘undefined’ is not a function (evaluating ‘fields.addClass(‘sortable’).sortable({
update: function(event, ui){
update_order_numbers();
},
handle: ‘td.field_order’
})’)
‘

Thanks a lot !
