Did you get this Warning/Notice? :
Deprecated Warning : Assigning the return value of new by reference is deprecated in * on line *
In PHP5 this notation is deprecated
$obj =& new Class();
That would generate the warning but ‘&’ is not required and can be removed.
$obj = new Class();
To see why this was used in PHP4, see http://www.php.net/manual/en/oop4.newref.php
