Please, try reading this article,

I’ve found the third in the list to work for me and solved my problem before so give it a try and see.

my problem is different.
Warning: Cannot modify header information – headers already sent by (output started at ../public_html/wp-includes/pluggable.php:1132) in ../public_html/wp-includes/comment.php on line 586
this error line is:
586. 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 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.
