Really like the plugin and hope it is still supported. I'm seeing the following error generated by the plugin (I've verified it is just this plugin producing the errors):
Notice: wpdb::escape is deprecated since version 3.6! Use wpdb::prepare() or esc_sql() instead. in /home/me/public_html/me.org/2013/wp-includes/functions.php on line 2900
Any ideas of a fix?
