        The database where the package was created has a <b><?php echo htmlentities($subTitle); ?></b> that is not supported on this server. 
        This issue happens when a site is moved from an newer version of MySQL to a older version of MySQL. 
        The recommended fix is to update MySQL on this server to support the character set that is failing below. 
        <b>If this is not an option for your host, then you can continue the installation. Invalid values will be replaced with the default values.</b>
        For more details about this issue and other details regarding this issue see the FAQ link below.
