I am afraid that whatever is going on with your theme and half a dozen apps you got mixed up in there, it is not working on many more levels - over 200 errors on initial load, count keeps increasing. Site usage is broken or compromised in many places besides image sliders.
I'd consider hiring a Shopify Expert to setup your theme and a few apps for you.
Did you buy this theme from the Themeforest?
I would suggest you reaching out to the theme developer, though I guess it may be unsuccessful, since their demo store has some of the errors you have in your store.
In this case I would recommend you to talk to Themeforest and ask for refund, since the theme code has errors (I've seen this several times and money refunded).
Then my recommendation (if on a budget) would be to either pick a free theme from the Shopify store (BTW, Shopify-made themes come with one hour of free design time!), or one of the better themes in the forest (At least one of them has a rep here in the forums -- Shella from @MPI_themes).
