When I go to the profile page and click ”update profile” button without change anything, I got
“ERROR: couldn’t update your profile…” but the mysql_errno is 0 at that time.
It seems when there is 0 row affected by Update, mysql_query() will return error. Maybe someone already found it, but how to fix it gracely?
In wp-db.php, I found the wpdb->query() return the rows affected. This should be the really reason for such a error.
