i am desperate to fix this, my client is going nuts at me.
It seems we lost the ability to remove an existing image and then replace it with another in cornerstone initially.
That's a pretty simple basic function, however, the client complained that when they "closed" an image with the 'x' that the media browser would not launch when they hit the '+' that replaced it.
I updated the site to pro and even moved it to my test environment on php 7 and still the media browser won't launch.
Anyone have any idea how I can fix this?
