This problem turned up when I tried running WordPress 2.0.2 with PHP 4.4.2 on Linux. However I also tried PHP 5.1.1 on Windows XP and everything worked perfectly (same version of WordPress).
Maybe it’s an issue/bug that PHP 4.4.2 is having with nested includes/requires. Or else it might be that PHP4 is having problems working on Linux.
I tried, but couldn’t figure out how to fix it.
