BUG: If you changed port from 80 to another one. VHost is not working (no replies)

using: EasyPHP DevServer 14.1 VC 11
PHP: 5.4.27
Apache: 2.4.7
Virtual Hosts Manager: 1.4

If you install EasyPHP DevServer 14.1 VC 11 and use default port for apache 80.
It's work fine.
Then install Virtual Hosts Manager 1.4 and add some new vhost then restart apache.

So you just change port for apache then vhost you set up before is not working.
I saw in the code of Virtual Hosts Manager. This is a BUG which Virtual Hosts Manager is not take case about apache port.

How can i contribute this?
