   setcookie(‘comment_author_’ . COOKIEHASH, $comment->comment_author, time() + 
   $comment_cookie_lifetime, COOKIEPATH, COOKIE_DOMAIN); if it were header problem,
   than i couldn’t leave comments as registrired user without errors

 * Have you tried:
 * – deactivating **all** plugins to see if this resolves the problem. If this works,
   re-activate the plugins one by one until you find the problematic plugin(s).
 * – switching to the default theme to rule out any theme-specific problems.
 * – [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)
   by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause
   problems.
 * And why are you running an older copy of WordPress?

 * esmi your way is right… i find the problem plugin it is qtranslate! but i can’t
   without these (( my older version of WP is for this reason: one of my languages
   is Georgian and there is no new wp version for Georgian language.
