Hey...I think this is either a very simple, or very complex problem...
Using the basic DB connect code:
$db =& DB::connect($dsn);
is making my pages just die. No errors, just a blank page. Error reporting, and display errors are on in php.ini, and I can get errors on other pages, but I'm not getting anything from DB.
Also, DB.php appears to be including properly. It's a bit of a mystery to me.
