1) I have installed the default version of our theme for you. Check and let me know if you need anything else.
2) That plugin gives js error even with default theme http://prntscr.com/hk961r this error breaks some scripts and that’s why such elements as slider, background video and some other do not work. So, either contact plugin author to fix this error or disable plugin. Because you won’t be able to use theme and some plugins because of this problem.
