Pictures after upgrade

I have installed ISPConfig 2.1.2 on an FC-4 server and it is up and running but it doesn't show any of the pictures in the boxes also i cannot get any access to the server settings.

I followd the recomandations in some of the posts here, and changed https://hostname:81 to https://serverIP:81 in the file config.inc.php
It worked perfect, all the rest worked perfect too.

Then I upgraded to the latest release, ISPConfig 2.2.0, the pictures didn't show up here alse, so I changed the new config.inc.php also to https://serverIP:81 but this time it didn't work, the pictures still doesn't show up.

How can I solv this?

 

I think I found the solution here: http://www.howtoforge.com/forums/showthread.php?t=2829

I changed:

$go_info["server"]["dir_trenner"] = "/";
$go_info["server"]["server_root"] = "/home/admispconfig/ispconfig";
if(isset($_SERVER['SERVER_NAME']) && isset($_SERVER['SERVER_PORT'])){
$go_info["server"]["server_url"] = 'https://'.$_SERVER['SERVER_NAME'].':'.$_SERVER['SERVER_PORT'];
} else {
$go_info["server"]["server_url"] = "https://serverIP:81";
}
$go_info["server"]["include_root"] = $go_info["server"]["server_root"] . $go_info["server"]["dir_trenner"] ."lib";

to this:

$go_info["server"]["dir_trenner"] = "/";
$go_info["server"]["server_root"] = "/home/admispconfig/ispconfig";
if(isset($_SERVER['SERVER_NAME']) && isset($_SERVER['SERVER_PORT'])){
$go_info["server"]["server_url"] = 'https://'.$_SERVER['SERVER_NAME'].':'.$_SERVER['SERVER_PORT'];
}
$go_info["server"]["server_url"] = "https://serverIP:81";

$go_info["server"]["include_root"] = $go_info["server"]["server_root"] . $go_info["server"]["dir_trenner"] ."lib";

Can someone tell me if this is completely correct?
