Hi there,I get the following warning (and some more) whenever I add an article using mod_k2_content_tag-.Warning: Parameter 2 to plgContentNavigation() expected to be a reference, value given in /opt/lampp/htdocs/NuevaAlcarria/libraries/joomla/event/dispatcher.php on line 136I get the same warnings but naming plgContentVote(), plgContentAllWeblinks(), etc..I've been searching around for a way to fix it, and I think it's related to my php version (5.3.0). My K2 version is 2.2, and Joomla 1.5.15.I hope someone can help me.Thanks a lot!
