Hi All I`m new on this forum.

I using: Joomla v 1.5.13
ARTIO JoomSEFv3.3.5 free
php 5
host: superhost.pl/

The problem is with my page www.cyeweb.pl. The first page is correct but when you click another link You will see error: Fatal error: Call to undefined function: array_diff_key() in /users/amb/www/cyeweb.pl/components/com_sef/joomsef.php on line 616

In file joomsef.php is :
if (!empty($newVars) && !empty($vars)) {
// If this was SEF url, consider the vars in query as nonsef
616: $nonsef = array_diff_key($vars, $newVars);
if (!empty($nonsef)) {
$mainframe->set('sef.global.nonsefvars', $nonsef);
}
}


I have read that is a problem with php 4 , but I useing PhP5 :(
Please help me what I did wrong!

Generally, I recommend you to move to host with PHP 5.2.x. Next versions of Joomla and also many components will not work with older versions of PHP. This is because of major object-oriented improvements in 5.2.0.
On the other hand, be carefull with PHP > 5.3.0. That can be problematic.
At the moment, for Joomla, PHP 5.2.x is the best choice.

Problem solved
