The errors are the only thing that show up on the page, that's the problem

The page is blank until I turn on all error reporting, and then I get the errors above.
It's running iis6 on win2k3, w/ the latest download of php from php.net.
I'll see how effective the spiders are, and hopefully figure out a way to get the PHP accelerator w/ the spider hack working properly. Without the spider hack the accelerator works fine...
