I’ve been trying to test this theme, but I can’t launch it. What am I doing wrong?
Debug screenshot:
You tagged the thread as Kirby 3 but looking at the error, its actually running a slightly older version of Kirby 2. Try updating Kirby to 2.5.12 and see if the error persists, and ideally use PHP 7.1.
It could also be an outdated version of Shopkit, which seems to be causing the error. You could try updating that too.
Looks like that theme was built for Kirby 2.1.0, so you may need to tweak some things.
simply downgrading MAMP’s preference to PHP 7.1 solved it! <3
