Need help with Warning: mysql_set_charset(): Error executing query on my wordpress website?

Warning: mysql_set_charset(): Error executing query in /home/titvar/proenablehealth.com/wp-includes/wp-db.php on line 782

Warning: Cannot modify header information - headers already sent by (output started at /home/titvar/proenablehealth.com/wp-includes/wp-db.php:782) in /home/titvar/proenablehealth.com/wp-includes/pluggable.php on line 1207

and this is the relevant code block

    if ( ! isset( $charset ) )
        $charset = $this->charset;
    if ( ! isset( $collate ) )
        $collate = $this->collate;
    if ( $this->has_cap( 'collation' ) && ! empty( $charset ) ) {
        if ( $this->use_mysqli ) {
            if ( function_exists( 'mysqli_set_charset' ) && $this->has_cap( 'set_charset' ) ) {
                mysqli_set_charset( $dbh, $charset );
            } else {
                $query = $this->prepare( 'SET NAMES %s', $charset );
                if ( ! empty( $collate ) )
                    $query .= $this->prepare( ' COLLATE %s', $collate );
                mysqli_query( $dbh, $query );
            }
        } else {
            if ( function_exists( 'mysql_set_charset' ) && $this->has_cap( 'set_charset' ) ) {
                mysql_set_charset( $charset, $dbh );
            } else {
                $query = $this->prepare( 'SET NAMES %s', $charset );
                if ( ! empty( $collate ) )
                    $query .= $this->prepare( ' COLLATE %s', $collate );
                mysql_query( $query, $dbh );
            }
        }
    }
}

in the wp-config.php file define('DB_CHARSET', 'utf8mb4');

how do i check if the database has same charset or not?

You'd have to access your database somehow. Depending on your hosting provider, you may have access through phpMyAdmin. Anyway, try changing the config file to utf8 and try again. If it doesn't work, check your database.

What's your charset set to in your database and what's it set to in your wp-config.php file?

They should both be the same, if they are not, try setting them both to utf8.
