PageMethods is not Defined in ASPX Page

Question

I\'m looking at some old code that I can only assume worked at one time.

MyPage.aspx:

function GetCompanyList(officeId) {
    var co         


        

Answer 1

One answer from another solution that I think should be represented is if this error occurs on your server but not locally is to place the empty MyPage.aspx placeholder file and now it works on the production server too.
