ahh your running PHP 5.3 i assume? 5.3 introduced some major changes and broke a lot of scripts including the super popular maggpieRSS which is what is producing that error. Options: You can suppress the deprecated error warnings (posted below), remove the RSS importer until maggpie is PHP 5.3 ready, downgrade to PHP 5.2.x
surpressing is probably the easiest
put error_reporting(0); at the top of stats.php
if your server config allows for user php.ini
Put a semicolon(
before the line "error
_reporting ="
