Web ftp not working

Hello,

I have a server with CentOS Linux release 7.4.1708 (Core) with CWP installed. The web FTP webftp_simple never worked for me.
This server has NATd IP configuration,

I have tried to change the parameters in index.php of webftp_simple like the FTP host from 127.0.0.1 to the Public IP address and also to Private IP address on server. but still no effect

Ok

I think I got it fixed, Public IP address in index.php parameter, restarted apache and FTP . that gives me access from web ftp.
