Hi, Ludwig!
1.)
Unfortunately, currently, you can change it only using the custom CSS code.
(I have already added this option in my TO-DO list for the next theme update)
so, for now, if you want to change the slider background image, insert the following code into
Customizing->General->Additional CSS:
.hero-slider{ background:url(https://images.wallpaperscraft.com/image/blue_light_line_65813_1920x1080.jpg)!important;
/* Center and scale the image nicely */
background-position: center!important;
background-repeat: no-repeat!important;
background-size: cover!important;
}
Change the URL address to your image.
As for the problem with the child theme and Fury Pro plugin, I have contacted our head developer to check that for me.
As soon as I get a response from him, I’ll let you know immediately.
Thank you for your patience.
Best regards
