I have 3 distinct forms in my website and they are built with Ninja Forms Lite Version 1.3.4. When I clone this site (with Add Clone Sites for WPMU (batch) plugin)this error is displayed:
Warning: Missing argument 2 for wpdb::prepare(), called in /var/www/wordpress/wp-content/plugins/ninja-forms/includes/display_functions.php on line 11 and defined in /var/www/wordpress/wp-includes/wp-db.php on line 990
Does anyone had this problem before? Do you know how to solve it?
Than you in advance!
