Thread:Extension talk:S5SlideShow/Call to a member function getHeadItems() on a non-object

Hi,

I get following error message when I click on "Slide Show" link:

Fatal error: Call to a member function getHeadItems on a non-object in /webdocs/w/extensions/S5SlideShow/S5SlideShow.class.php on line 371

I have MediaWiki 1.20.2, PHP 5.3.21 (apache2handler). Any ideas?
