@joeltransky Greetings, do you put this in the child functions.php or the parents?

This goes into your parent theme. Very useful.

Wow, is this in the ACF documentation? I've been searching for a solution for a long time, trying to understand why a simple child theme (with just the style.css file) was crashing my WordPress site with the PHP fatal error: "Allowed memory size of X bytes exhausted". Thank you so much for the code snippet! 😄
