    You can configure the max file upload with the security settings, but a value above 28 Mb is not accepted. So I changed the settings in the web.config (maxRequestLength), but only values below 28 Mb are reflected in the UI security settings, and what's a bigger problem, also not reflected in the file upload within the site assets. 

    Is this a bug? (I've checked versions from 9.3.2 uptil 9.81 but no improvement on this subject).

      Hi Peter,

      I found this in the code of DNN, in the method DotNetNuke.Common.Utilities.Config.GetMaxUploadSize:


      
if (httpNode == null && Iis7AndAbove())
      
{
      
    const int DefaultMaxAllowedContentLength = 30000000;
      
    return Math.Min(maxRequestLength, DefaultMaxAllowedContentLength);
      
}


      So it's definitely intentional, but I don't know why that is. Maybe you can create an issue on GitHub so it can be discussed wether or not this is something to fix?

        On IIS7+ you need to add a node to specify the maxAllowedContentLength for requests.
        (maxAllowedContentLength  = Bytes)

        Add this to your web.config:

        < system.webServer>
            < security>
              < requestFiltering>
                < requestLimits maxAllowedContentLength="2147483647" />
              < /requestFiltering>
            < /security>
        < /system.webServer>

          But even then, DNN still seems to use 30000000 as a maximum...

            DNN ver. 09.10.02

            So is it possible to upload files over 28Mb ?
