ACF and ACF pro not working on my Nginx server with php7.2-fpm.
Trying to access “custom fields” tab, or trying to edit any page shows an error The site is experiencing technical difficulties. Please check your site admin email inbox for instructions.
I checked my nginx error log, this is what I’m getting:

I had forgotten to add my PRO license key!
I added the key, updated to the latest ACF Pro version and now everything works.
It did work on my local machine without the key, so that confused me.
