Perfect, as always John! Either solution solves my issue.
Perfect! Great solution John, thanks for the help.
I’m experiencing this exact same issue. I have a Post Object ACF group on a page and when I drag and drop to rearrange the chosen posts this error (below) is thrown.
I do not “believe” its an issue with my theme — just using Underscores base theme.
I’m running the latest version of ACF Pro (5.9.5) and latest WordPress version (5.6.2)
Error msg:
