Hey, I used this tutorial http://www.compassdesigns.net/joomla-tutorials/css-drop-down-menu to make a dropdown menu in my Joomla! site, together with this module: http://de.siteof.de/detree/extended-menu.html The only thing I'm seeing on my site is a lot of error messages, such as Deprecated: Assigning the return value of new by reference is deprecated in C:\wamp\www\Joomla!\modules\mod_exmenu-j15\exmenu\exmenu.class.php on line 56 Does anyone know what went wrong and how to solve this problem? Or does anyone know any other Joomla!-modules for a dropdown menu?
