I’ve been check your site again. You have Jkreativ theme v2.3.6 in there but you have VC plugin v4.11. It seems you’re not using VC plugin that come with our theme right? Anyway please try to update your theme into v2.3.8 and we’ve been include VC plugin v4.11.2 on theme package. We will suggest you to use VC plugin that come with our theme for compatible reason.
