Slider revolution look empty and black - by John Becker

Hello,

Thanks for contacting us.
Set category of products here – http://prntscr.com/ts7hla
Provide temporary wp-admin access, I will re-import the second slider on your page.

Regards

Hello,

1) This slider shows products based on selected category – http://prntscr.com/tskjls , so you need to create your own products with images – https://docs.woocommerce.com/document/managing-products/
Read more in docs of the Slider Revolution plugin – https://www.themepunch.com/support-center/
2) Theme Options > Header builder > edit content of the header.
We used a simple menu widget, for the demo only, just to inform user that he could place switchers in that area. If you want to create the multilanguage site you need to use special plugins like WPML or Polylang or qTranslate or any similar and add special widgets that come with these plugins to header area.
Follow our docs to translate the theme – https://www.8theme.com/documentation/xstore/theme-translation/
3) It is correct. Shop page is WooCommerce archive page that does not have any content. WooCommerce displays product there automatically, it’s not in the page content. You can’t edit the products on the shop page using page editor. If you want to change the layout of the shop page use theme options: Theme Options > WooCommerce.
