I checked my php.ini settings. I don't know how to make shore if dom extension is activated or not beacause as i know it comes on php core from php 5.2.1. The only thing i'm shore about is that domxml extenssion is activated.

I'm using wamp 2:
apache 2.2.11
php 5.2.9
mysql 5.1.32

Thanks in addvance for any help.
