stumped. i really need help.

[Hall of Famer]

I see, if u are running PHP 5.3.0 - 5.3.8, u may get this abstract method inheritance error. It's very easy to fix, just open the abstract class files and remove the abstract methods. In ur case for instance, open the collection.php class file and get rid of the abstract method called iterator(). I am sure u need to fix more than this, just keep following the instruction above until all abstract methods causing errors are removed.
