Hi, lovely theme!!! And I see you are very good with support :-)
I can't make the featured slider + row of posts show up in Home (static page) - empty or with some text in page: nothing.
I've tried 'standard-template' and 'full-width'.
The posts are marked 'sticky', the featured images are set.
I see 'Custom field' layout_key + post_slider_check_key are there (I didn't touch these): do I have to define something else?
I haven't activated other 'slider/slideshow' plugins yet.
I have a child-theme.
