Whenever I update a field group using ACF in a custom post type, my posts disappear from the backend. I made three It says All(3) and Published (3) yet I cannot see any of them. they still appear on the front end of the website. Anyone else have this problem or is this a CPT issue? Thanks!
It sounds like you have a pre_get_posts filter running that is preventing the posts from being seen in the admin. Have you added anything like this to the site?
