ACF flexible content block not showing on live site (works locally)

I've made a flexible content section in ACF for a specific category that allows the user to post text and different image galleries onto their post. This all works perfectly whilst I'm on my localhost but now I've uploaded the site none of the content is showing.

My code is quite messy but the code in my single.php is below and this is the link to a live post https://www.exoticsoftware.co.uk/2021/12/01/pendas-fen/, the only things that show on the page are the post thumbnail (haven't added a post thumbnail to this, so that's why that's missing) and the post title, there's also a section at the bottom which should loop through two other posts but that isn't showing, the footer also isn't showing on this page but does work on other pages?

When I inspect the page none of the code is there - I don't understand what is missing that is causing this to work fine locally and then not at all on the live site.,
