Designs can be changed even on-fly by simply adding the following code to the address bar:
?skin=mcl
or
?skin=def
or
?skin=ae3
or
?skin=ae4
or
?skin=dlt
"mcl", "def", "ae3", "ae4", "dlt" represent the five default design layouts that are available now.
In fact, now design can be switched even by a user.
If you want to switch the default design, open the "header.inc.php" file, find the line
$tmpl = "mcl";


and enter the necessary design code.
If you want to disable the on-fly design switch feature find these lines of codes in this file and comment them out or delete
// change skin
if ( $_GET[skin] )
{
$tmpl = $_GET[skin];
setcookie( "skin", $_GET[skin], 0, '/' );
}
else
if ( $_COOKIE[skin] )
$tmpl = $_COOKIE[skin];
