Well... now I'm going out of my mind. Now it actually works. I don't know
what I've changed, but for some reason now it all works perfectly. As
someone suggested, it might have been a problem with the casing, ie.
different casing in the filename, since at some point I copied the require
statement from the other to the other, and later it started working. I gotta
try to find an earlier copy from backups to see if it was a case of cases
indeed.
By the way, someone asked about the versio, I'm running PHP 5.0.5 with IIS6
on a Windows 2003 Server.
Thank you all for replying. I'll let you know if I can backtrace the
problem, but at the moment I strongly suspect that it actually was something
like spelling it require_once('eKirje.boxContainer.class.php'); in one file
and require_once('eKirje.boxcontainer.class.php'); in the other. Blasted
case-insensitive filesystem. In a *nix server this wouldn't have happened,
since case matters in filenames.
