I also called the LoadLanguage, LoadLanguageSelect, LoadVideoLogLay and LoadImage javascript methods in javascript's pageload method. When the page loads in this way, the actions in those methods will work during page loading. But I get this error when posting javascript methods to asp.net cs side.

My javascript's pageload method

        function PageLoad() {
            LoadLanguages(1);
            LoadLanguageList();
            LoadImageGallery();
            LoadVideoGallery();
        }

And my methods in Javascript

 function LoadLanguageList() {
            $.ajax({
                url: "Edit.aspx/LoadLanguageSelect",
                dataType: "json",
                data: "{}",
                contentType: "application/json; charset=utf-8",
                method: "POST",
                success: function (result) {

                    var xmlDoc = $.parseXML(result.d);
                    var xml = $(xmlDoc);
                    var languages = xml.find("Table");
                    $('#select_AddLang').empty();
                    if (languages.length > 1)
                        $('#select_AddLang').append($("<option></option>").attr("value", 0).text("Choose a language"));
                    else if (languages.length == 0)//All languages has already been added.
                        $('#select_AddLang').css("display", "none");

                    languages.each(function () {
                        var language = $(this);
                        $('#select_AddLang').append($("<option></option>").attr("value", language.find("Ix").text()).text(language.find("Name").text()));
                    });

I see two issues

First I noticed that your WebMethods do not accept parameters but you are specifting data: "{}" in your ajax call. Try omitting this line when parameters are not necessary. You could return a 404 if the page is looking for a method which accepts an object but doesn't find one. See this answer:

How to call c# method with no parameters and access returned data?

Have you tried using fiddler to watch your AJAX request being made? If so ensure that it is actually going out as a POST request. Otherwise the sever will be searching for a GET method and will not find one, thus returning a 404.

I always use $.ajax({type: "POST""}); as opposed to $.ajax({method: "POST""})
