Hello,

the example you provide for WFileUpload causes the error message

[Wed Oct 12 13:14:27.746877 2016] [fastcgi:error] [pid 29824:tid 140164269516544] [client 127.0.0.1:57547] FastCGI: incomplete headers (2 bytes) received from server "/usr/lib/cgi-bin/tc/tpc", referer: http://localhost/cgi-bin/tc/tpc

and the progress bar does not work. The file is uploaded, though. Any ideas why that is? Code is as follows.

Thanks for your help,

Michael.
