/*
	Plugin Name: Divi Theme Config for Pantheon
	Description: READ THIS BEFORE UTILIZING - This plugin is still in the testing phase, and contains rules for turning 
	off Divi Theme Features by default known to cause issues within the Pantheon environment. Cyrus has created a 
	separate mu plugin for the Divi Page Builder that can be found here. 
	
	https://github.com/hckia/divi-page-builder-configs 
	
	Both Divi theme and Divi page builder plugin attempt to purge et_cache of static resources before any 
	changes are implemented, exacerbating the very problem trying to be addressed. By installing this as an mu-plugin, 
	the settings are implemented and enforced early enough in the bootstrap process, but a manual 
	purge of et_cache will still be required. Future modifications may be done by Pantheon.
	
	Version: 0.6
