Warning: mysql_real_escape_string() expects parameter 1 to be string

  • Hi,

    I use this plugin :

    • WP Category Permalink v 1.6
    • WordPress 4.0.1

    With this custom url Permalink
    /%category%/%postname%/

    But some problem on Permalink config page :
    Warning: mysql_real_escape_string() expects parameter 1 to be string, array given in /home/arseneeh/creai/wp-includes/wp-db.php on line 1040
