Warning: Parameter 1 to modMainMenuHelper::buildXML() expected to be a reference
At present Joomla! is not certified to work with PHP 5.3.0. If you see this error message on your Joomla website, probably your web host is running PHP 5.3 or recently upgraded to PHP 5.3 (which was my case).
To fix this, go in the helper.php file (/modules/mod_mainmenu/helper.php) and change
function buildXML(&$params)
to
function buildXML($params)
Now the error should be gone!
