Sad sam malo pogledao na Google oko ovog errora, ne razumijem se u php ali kaže ovako
When chosen mysqli in the first step of setting up 5.0 beta 2, if Zend 1 compatibility mode is on it gives a fatal error:
Trying to clone an uncloneable object of class mysqli in /path/to/drupal5.0/includes/install.mysqli.inc on line 36
This is a problem with PHP5 directive more than a Drupal bug, but setting an error handler will be a good idea.
When using Zend Compatibility Mode, you'll not be able to use MySQLi as you would like. Each time you try to create a new object you'll get:
"Fatal error: Trying to clone an uncloneable object of class mysqli in XXX".
In order to use the mysqli objects you'll need to deactivate Zend Compatibility mode before calling the connect procedure:
ini_set('zend.ze1_compatibility_mode', 0);
$mysqli = new mysqli(hostname,username,password,[database]);
** Issue happening under Unix and Windows OS.
Google search indicates that you need to disable zend.ze1_compatibility_mode in the PHP.INI file on the server generating the error.

izgleda da je problem u nekakvom Zend Compatibility modu koji valjda treba deaktivirati, ako sam ja ovo dobro shvatio, s tim da instalacioni direktorij foruma nema fajl php.ini gdje bih to mogao čačkati
