Fatal Error: Call to undefined function wp_print_notices

The plugin is throwing a fatal error:

Fatal error: Uncaught Error: Call to undefined function wc_print_notices() in /var/www/html/wp-content/plugins/woo-add-to-quote/shortcodes.php:17

require_once('functions.php'); in the main plugin file woo_add_to_quote.php should be wrapped in a check to see if WooCommerce has been loaded because plugins load at different times.

You might want to consider wrapping that in a function that gets called on the plugins_loaded hook or refactor the watq_check_if_woo_is_active function a little bit to include the include.

Something like this would work without refactoring the watq_check_if_woo_is_active function.

function watq_load_functions() {
    if ( class_exists('WooCommerce') ) {
        require_once('functions.php');
    }   
}

add_action( 'plugins_loaded', 'watq_load_functions' );
