1. Backup files and database
2. Update theme (delete “woocommerce” folder, which is located in wp-content/themes/woopress/ to avoid problems with old files)
3. Update plugins
4. Create an empty dynamic.css file in woopress-child theme folder and set permissions 777 for the file + add wp_enqueue_style( 'dynamic-css', get_stylesheet_directory_uri() . '/dynamic.css' ); in woopress-child/functions.php file. Then go to Theme Options and re-save them
