Pascal, Have you modifed your web.config when upgrading?There are a lot of changes in the version 5.x DNN provider.  

Sorry to seem like a dunce, but in which section of the web.config should I add the entry (i.e. what is it a child of?).   Thanks.   Aaron

Hi,   So , you did add UploadModule into web.config , ?   --   If so , I think your IIS setting do not allow *.axd handler .   Regards, Terry  

The folder is the one specified in the web.config as TempDirectory:   <add key=''CuteWebUI.AjaxUploader.TempDirectory'' value=''~/Downloads''/>   Is there where uploads are supposed to be saved?

Hi Kenneth, how i can this !!! Regards Megami59

Austech,   Try set the following section in the web.config file: ==========<system.net><settings><httpWebRequest useUnsafeHeaderParsing=''true'' /></settings></system.net>==========   Keep me posted    

Nick,   Thanks for pointing the problem. We juse fixed that. We redesigned our site recenlty. We miss a dictionary entry in the web.config file which cause the problem. Sorry for the inconvenience.        

I checked the version. It is the same. I replaced my code in the web.config file with the code you posted. Now I get this error. A critical error has occurred. Check your provider configuration for errors! Could not find file ''C:\Develop\DNN_3.1.0\1.css''.
