Slider images not visible

Im using Customizer 3.4.16 on directory based multisite – https://thejunction.net/rightandwrongjournal/
It worked in the past.

I can see slider image edit placeholders moving across screen with admin toolbar enabled.

I’ve deleted & uploaded new images for slider use and deleted and recreated new slider and cleared site cache and browser cache with no luck.

Ive deactivated plugins and turned off image retina activation as well as turned off wordfence briefly to test, which has always worked in past with theme slider.

I use another slider on site Huge-IT slider and disabled it to test with no luck.

Ive also turned off responsive images for slider setting even though I utilize different mobile homepage.

Help help help please – I’m stumped!
