Frequent error DB table does not exist

Hi thanks for your plugin and hard work.

We’re seeing frequent errors stating:

WordPress database error Table ‘DB_NAME.mp_options’ doesn’t exist for query DELETE FROM
mp_options WHERE (option_name LIKE ‘%_rfqtk_wp_session_expires_%’ OR option_name LIKE CONCAT(‘_rfqtk_wp_session_’, replace(option_name,’_rfqtk_wp_session_expires_’, ”)))

Seems this is coming from your delete_old_sessions function around line 100 in class-wp-session-utils.php.

	public static function delete_old_sessions( $limit = RFQTK_WP_SESSION_CLEAN_LIMIT ) {

...

            $sql= "DELETE FROM 
        mp_options WHERE (option_name LIKE '%_rfqtk_wp_session_expires_%'  OR option_name LIKE  CONCAT('_rfqtk_wp_session_', replace(option_name,'_rfqtk_wp_session_expires_', ''))) 
        and option_value <=%d    LIMIT %d";

...
}

Thanks for taking a look.
