Unable to save result set in .../wp-includes/wp-db.php

Arkadaşlar sitemde 2 uyarı alıyorum bilen varmı?

Warning: mysql_query(): Unable to save result set in ../wp-includes/wp-db.php on line 1879

Warning: Cannot modify header information - headers already sent by (output started at ../wp-includes/wp-db.php:1879) in ../wp-includes/pluggable.php on line 1195

bütün eklentileri silip(ya da plugin klasorunun adini degistirip) veritabinini onarmayi deneyin

teşekkürler hocam
