PHP errors on settings update

I’ve noticed consistently that when I go to change the settings in the admin console I get this error:

Warning: mysql_real_escape_string() expects parameter 1 to be string, array given in /home/example/public_html/wp-includes/wp-db.php on line 1036

Warning: mysql_real_escape_string() expects parameter 1 to be string, array given in /home/example/public_html/wp-includes/wp-db.php on line 1036

Warning: Cannot modify header information - headers already sent by (output started at /home/example/public_html/wp-includes/wp-db.php:1036) in /home/example/public_html/wp-includes/pluggable.php on line 1178

Can you please look into this and address the issue? Thanks
