500 internal error when creating new server

[Roccamio]

Hello,

Thanks for this helpful module.

I encounter a 500 internal server error when I try to make a new VPN server (not with simmetric key)

Below is the log of the /var/webmin/miniserv.error
/openvpn/create_vpn.cgi : Missing Content-Type Header
cat: current: No such file or directory
cat: current: No such file or directory

I had a look on new_vpn.cgi, but I cannot found the error by myself.

Any idea about this issue?

Thanks by advance for your answer.

Regards,
Rocca
