Place a slider in front page

What theme are you using? Where did you download it from? Are you using a plugin for the slider?

I am using Avada theme , it is just a jpg background and I am not using a plugin.Thanks

I’m sorry but as you appear to be using a commercial theme, you need to seek support from the theme’s developer/vendor. We do not have access to, nor do we support, commercial products here. Try https://themeforest.net/item/avada-responsive-multipurpose-theme/2833226/support
