Answer 1

Try specifying the path as the next parameter.

setcookie('sm_posts['.$key.']', '', time()-60*60*24*365, '/');

Do this for BOTH cookie settings statements (and manually delete all your existing cookies).

But a better solution is to use the WordPress defines for this, COOKIEPATH and COOKIE_DOMAIN.

setcookie('sm_posts['.$key.']', '', time()-60*60*24*365, COOKIEPATH, COOKIE_DOMAIN);

(Again, manually delete all the existing cookies)

Answer 2

Try it this way

foreach($_COOKIE["sm_posts"] as $key => $value)
 {
    setcookie ("sm_posts['".$key."']","", time()-60*60*24*365);
 }

I think it because of your quotes
