Hi !! I'm a new one... ..... why this error ?? the server's GAC has it ?? Could not load file or assembly 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
are you hosted on IIS7? iis7 does not have ajax 1.0 installed; it only has ajax 3.5. 1.0 is kinda old and I recommend you update your app to use ajax 3.5. If you must use 1.0, we can move your site to IIS6 or you can try uploading the 1.0 dll into the bin dir.
