Kimmo,
That should work just fine.
First of all, please check the case on each of your require_once
statements. Are they the same? If the case is different, PHP will
think it's two different files. Also if the path has changed PHP may
consider them to be different files.
Perhaps if you copy/paste the actual require_once statements so we can
see exactly what you're doing.
Also, what version of PHP are you using?
