Hi @katawura
I need more information to understand what’s going on.
You have created one or more field groups with ACF fields. You go to a post (for example), insert values in the ACF fields and when you click update (or publish) the ACF fields are not saved?
If you have the latest version of ACF and WordPress I’m going to guess that you have an issue with another plugin or possibly your theme.
Could you try disabling all other plugins first to see if that solves it?
