Slider revolution not visible if not logged in (after update)
I´m working on this website https://www.home-cockpit.de/, where we are using a Slider Revolution on the header. After updating the theme the slider only shows, when I´m logged in... otherwise you only see a blue-screen.
See screenshots attached, please.
I´ve already tried deactivating the plugins, updated everything... but no effect.
Could you please help me out?
Many thanks and best regards,
