You can fix the install script by updating the command in install.sh
or you can disable the https redirect.
You can comment this part in index.php:
if(!isset($_SERVER["HTTPS"]) || $_SERVER["HTTPS"]!="on") {
$server = $_SERVER["HTTP_HOST"];
if($server != "localhost" && $server != "127.0.0.1")
header ("Location: https://".$server.$_SERVER["PHP_SELF"]);
}
Also, take note that FreeSentral is no longer maintained. For all features to work you have to use it with yate versions between 3.0 and 4.3. The majority of the features still work, but not all.
