 * when clicking a new wiki link on my website it opens a new wiki page inner my
   wp site.
    i get this bug in the navigation area:
 * `Warning: in_array() [function.in-array]: Wrong datatype for second argument 
   in /.../www.xxxxxxxx.com/wp-includes/nav-menu-template.php on line 564`
 * i think its because of the plugin – anybody has some experience on this bug??
