After placing my uploader into my project I began receiving the following errors depending on my browser;

 

http error1 :405:Method Not Allowed

 

 http error1 :12031:Unkown 

 

I tried removing one part at a time from my page until my uploader worked. It turned out to be the Action="#" property within my pages Form tag. Any thoughts on why this is and a way to get around it?

 

Solution that worked for me was to change the '#' in the Action Property to the name of the page e.g. <Form runat="Server" Action="MyPage.aspx">

 

Hope that helps someone!
