Pantheon Avada broken CSS file issues

snippet.php

// This error occurred when transferring the Avada theme from an external host to pantheon. There was a MIME type error followed by a 404 on the homepage. I believe the random string pantheon uses for file struture differed from the other pages of the site.

Make sure WP_cache is off and added the addition if statement below to fix.

//define('WP_CACHE', true);

if (isset($_ENV['PANTHEON_ENVIRONMENT'])) {
    define('FS_METHOD', 'direct');
}
