        error: function(data) {
            var username = JSON.parse(localStorage.getItem('iguser'));
            var profilepic = JSON.parse(localStorage.getItem('iguserimg'));

            $('.box[data-the_id="' + theid + '"]').children('.postMessage').children('.messageComments').append('
' + username + '
' + dataString + '
