I have the same issue with ACF pro 5.6.3 / WordPress 4.8.2.
Like @magicstick :
If visual editor is default tab it’s not working (switching to text tab works)
If text tab is default, I can switch to visual tab and it works.
It’s a form in a user Add/Edit form. However I am pulling the acf_form to a front end template page and behavior is the same.
I’ve tried deactivating all my plugins apart from ACF. No change.
I’ve tried removing all other jQuery based fields from my field group. No change.
WYSIWYG working fine on pages flexible fields. (don’t get that at all)
I was expecting for a resolution with the last version of ACF last week but nothing change.
Console give me some informations about the problem but I don’t know how to resolve it.
I see that there is a simple problem of instance between each other:
acf-input.min.js:3:22419ReferenceError: Can’t find variable: instanceId
tinymce.min.js:14:3486TypeError: undefined is not an object (evaluating ‘a[b]’)
Do I have to open a ticket or this problem should be resolved in an other way?
Thanks a lot for your reply.
