The HTTP verb POST used to access path .... is not allowed

Question

I have a aspx file and I would like to request to WebMethod in same page with Ajax. However I get some error(you can see below) Actually this code worked before change my server.

Server config

• IIS 7.5
• .Net Framwork 4
• Windows Server 2008 R2

This is my Webmethod code in "Page.aspx"

[WebMethod]
public static string deleteOpenedSegment(decimal segmentID)
{
    bool success = Helper.DeleteSegment(segmentID);
    if (success)
    {
        return "true";
    }
    else
    {
        return "false";
    }
}

And this is my Javascript method in Page.aspx

jQuery.ajax({
       url: 'Page.aspx/deleteOpenedSegment',
       type: "POST",
       data: "{'segmentID':" + getSelectedSegment().attr('id') + "}",
       contentType: "application/json; charset=utf-8",
       dataType: "json",
       success: function (data) {
                  alert("okey");
                }
       });

And also this is capture about request from Google Chrome Web Developer Tool
