How to resolve the error “Query failed: Unexpected error from server.” in SharePoint 2013?

Question

The Create New Item is the custom icon created in the list. After migration from SP 2010 to SP 2013, on clicking the Create New item icon the below error is displayed.

The message reads:

"Query failed: Unexpected error from server. The status code from response is '403'. The status text of response is 'FORBIDDEN'. null".

Can anyone help me with this?

You can check if there is any custom script in your page which will cause this issue.

And For SharePoint 2013, you could try to use Rest API to create new list item:

    function SubmitListItem() {
        var title = $("#title").val();
        $.ajax
            ({
                url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/GetByTitle('MyList4')/items",
                type: "POST",
                data: JSON.stringify
                    ({
                        __metadata:
                        {
                            type: "SP.Data.MyList4ListItem"
                        },
                        Title: title
                    }),
                headers:
                {
                    "Accept": "application/json;odata=verbose",
                    "Content-Type": "application/json;odata=verbose",
                    "X-RequestDigest": $("#__REQUESTDIGEST").val()
                },
                success: function (data) {
                    console.log(data);
                },
                error: function (data) {
                    console.log(data);
                }
            });
    }

</script>
    Title: <input type="text" id="title">
