   Hallo,
   
   ich habe Joomla mit XAMPP auf meinem PC testweie installiert. Im Hauptmenü auf der webseite erscheint aber statt den Links:
   Warning: Parameter 1 to modMainMenuHelper::buildXML() expected to be a reference, value given in C:\xampp\htdocs\Joomla\libraries\joomla\cache\handler\callback.php on line 99
   
   die datei sieht so aus:

   Kann man diesen Fehler irgendwie beheben?

   Könntest du uns mal die komplette Klasse "modMainMenuHelper" zeigen?
   Der Methode buildXML dieser Klasse muss eine Referenz übergeben werden, was in Zeile 99 nicht passiert.
   Ich weiß aber auch ohne diese Klasse nicht, was für eine Referenz verlangt wird.
