you get that trying to upload? It looks more like a strange download error.

Can you reproduce the problem on our demo site?

Does changing the skin affect the problem?

You are using IE 11 and not using any old compatibility mode?

our file uploader depends on html 5 which is not fully supported by IE 8. If most of your users use that I think I would try adding this in user.config

<add key="ForceLegacyFileUpload" value="true" />

then touch web.config to make sure it sees that setting.

It should degrade to a more traditional upload with input type=file and one at a time file uploads without drag and drop and without use of the fille service url

Hope that helps,

Joe

Hi,

I just looked into this issue and have fixed it in my copy so it will be fixed in the next release.

In the meantime there is a workaround that also solves in my test.

If you edit the file with a text editor /SharedFiles/SharedFilesModule.ascx

look for this:

<portal:jQueryFileUpload ID="uploader" runat="server" />
 <portal:mojoButton ID="btnUpload2" runat="server" Text="Upload" OnClick="btnUpload_Click" EnableViewState="false" />

currently it is inside an updatepanel, but this kind of file upload can only work with full postback not with ajaxpostback of the updatepanel.

So you need to move it from where it is to below the closing tag of the updatepanel.

</asp:UpdatePanel>  

Hope that helps,

Joe
