I work at a non-profit where we teach underserved adults to be software engineers, and then we employ them. Their first paid projects are practice WordPress templates, and we build using x-theme/Cornerstone. Several of them have been getting continuous failed to save errors, and then all of their custom CSS disappears. Our senior engineers spent hours trying to fix it. We have cleared caches, read every article we could find, and added define( ‘WP_MEMORY_LIMIT’, ‘512M’);
define( ‘WP_MAX_MEMORY_LIMIT’, ‘512M’);
to the config files. That worked for one person only on my team. Please help!
