Hello James
Thank you for looking at my problem.
Here is what I have done:
– I have installed a new empty wordpress installation on my local machine using mamp. (Mac El Capitan, Mamp 3.5)
– I installed the Advanced Custom Fields plugin Version 4.4.8 only (no other plugins are installed)
– I create a custom image field for a post
– I go to the “Hello World” post, add an image and the click “Edit Image” from the post.
– I get a NaN selection
Here is a screenshot

I have tried it on many installations and on several computers. No javascript errors whatsoever. I don’t know what is going on.
Thanks
Mike
