I downloaded the zip again, unzipped it, and simply deployed it on our server. Without touching the code.
the bug is still there,uploads don't work.
 
I sent you a link by Eamil. I can't post the link here.
 
what about the tow other problems that also happen in your demo ( details in the original post)?
 
if I'm working on the wrong version please give me a link to the latest.
waiting for reply.
