I just upgraded three of my sites from 5.5.1 to 5.5.2.

First two upgrades went fine but now when I access the third site, I get following message on some pages:
Fatal error: func_get_args(): Can't be used as a function parameter in /public/html/concrete/libraries/item_list.php on line 515

Both these pages have a slideshow block in them.

What could be wrong? The Concrete5 navigation bar won't load on these pages.

My environment:
