a. find out php.ini
set register_globals = On
or try this
b. alter banner.php
add this
if (empty($op)){
$op = $_GET["op"];
}
if (empty($bid)){
$bid = $_GET["bid"];
}
before this line switch ( $op ) {
I have same problem on my server.
I try to set register_globals = On
It works, but I think they may cause a lot of security problem.
so I set register_globals = Off and try to alter banner.php to get $op and $bid from GET form.
It works too.
