Hi Lottiejam,
I have just solved the same issue for a website i was working on… the slider was not loading regardless of the fact i filled in the required URL’s
after a number of tests and messing with the base code of the theme, i determined my main issue was with the “if” statement at the bottom of the header page… i adjusted that statement to include one of the pages i was actually using for the “home” page, i.e. removed the archive option… and it worked… the way i tested if this was the issue was to remove the IF statement completely…
( is_home() || is_front_page() ) )
you may try and do the same or have to modify…
you are welcome to ask quesiton if you like or send me info on your site and ill see if i can help..
good luck
-Karen…
