Hello,
Our FTP user does not have permission to edit file https://gyazo.com/7eb4d40811e692ec289e295bb9ff6d1e
So, find
add_action( 'wp_enqueue_scripts', array( $this, 'enqueue_scripts' ), 20 );
and change it to
add_action( 'wp_enqueue_scripts', array( $this, 'enqueue_scripts' ), 40 );
in /wp-content/plugins/et-core-plugin/app/controllers/customizer.php
Or provide FTP with correct permissions.
Regards
