Database error display - how to change so that doesn't take over full page

[coffeesgr]

When the database error occurs, all the forum pages go to the database mysql error, and nothing else is displayed until the db can be connect again, and the problem is solved (by reboot). But when you use the integration file, using the forum global.php file, other pages of the website also just display the database error page, even though the only thing that needs to connect to the db for that page is whether the user is online or not. Where can it be changed so that the database error just is a one line error displayed, rather than not letting the rest of the page content to show - at least for pages that are not part of the forum and are just using the global.php file for integration to the forum.

Thanks.
