Hi @zartgesotten
Thanks for the bug report, however, I’m not sure why you are experiencing a core JS error when ACF is activated.
Have you tried swapping to a default WP theme to make sure the issue does not come from a conflict there?
Also, can you confirm that all other plugins are disabled when you see this error or are there still a few activated?
I only ask because this is the first occurrence of this issue, so I believe it will be specific to your install.
Thanks
E
