I have Mambo 4.6.1 Stable and upgraded from PHP 5.3 to PHP 5.6 and got this error:

Warning: Parameter 2 to frontpage() expected to be a reference, value given in C:\xampp\htdocs\mambo\includes\Cache\Lite\Function.php on line 100

Here is how I fixed it!

Open: /includes/Cache/Lite/Function.php

(this solves the "Reference instead of value"-problem)

Copy and Paste the code below and replacing the code in your Function.php file: 

<?php

/**
* This class extends Cache_Lite and can be used to cache the result and output of functions/methods
*
* This class is completly inspired from Sebastian Bergmann's
* PEAR/Cache_Function class. This is only an adaptation to
* Cache_Lite
*
* There are some examples in the 'docs/examples' file
* Technical choices are described in the 'docs/technical' file
*
* @package Cache_Lite
* @version $Id: Function.php 49 2005-09-15 02:55:27Z rhuk $
