Thread:Extension talk:S5SlideShow/bug: call user func ?/reply

Thanks about $IP, I've corrected the help page.

This is a strange error (PHP couldn't find a static function with "Class::method" syntax). What's your PHP version?

You can try to edit S5SlideShow.php and change

To

But I'm not sure it will work, as there are more places which use this syntax and which cannot be changed such easily ($wgHooks['xx'][] does not allow array('Class', 'function') syntax).
