 * Hi there!
 * I just installed Worpress SEO and now I get this error when I open my Post Editor:
 * Notice: Undefined offset: 3 in /homepages/34/d444938177/htdocs/wordpress/wp-content/
   plugins/wordpress-seo/inc/wpseo-non-ajax-functions.php
 * Everything works still (as far as I can tell), but I’d really like to know what
   that means and how I get rid of it!
 * Thank you very much and all the best,
    Pete

 * Hi Pete,
 * I am having the same issue with WP_DEBUG turned on… I’ll look into it. Hopefully
   by replying this will push the request to the top as well.

 * Notices aren’t a problem in the plugins, it only means the plugin isn’t checking
   that a certain array exists. A much bigger problem is the fact you’re running
   WordPress with debugging enabled, this could be massive security risk. Turn that
   off ASAP!!
