Решение

Требуется сделать то, что просят необходимо в файл mysql.php добавть следующую строку

<?php
	error_reporting(~E_ALL);

	/* UMI.CMS mySQL - connection to database */
	mysql_connect('rv.mysql', 'rv_mysql', 'rcijhzvy') or die(mysql_fatal());
	mysql_select_db('rv_vestiyug') or die(mysql_fatal());

	mysql_query("SET NAMES utf8_general_ci");
	mysql_query("SET CHARSET utf8");

	mysql_query("SET CHARACTER SET utf8");
	mysql_query("SET SESSION collation_connection = 'utf8_general_ci'");

	// именно эта стока решает проблему
	mysql_query("SET SQL_BIG_SELECTS=1");
?>
