Hi, I am having the same problem 🙁 I disabled ALL plugins and it still doesn’t work. I’ve no idea at what point this stopped working, I basically have a ACF and ACF: Gallery. I added some gallery images to a post (page actually) successfully, and now when I tried to add a new ACF image field it never saved. So I tried to go back and add images to the gallery ACF of another page and when I hit “update” the field disappears although my images are uploaded when I check my Media. Help!
