Just to make this clear - the PHP suExec Yes/No setting is under Configuration -> Server -> General -> Using Apache Configuration File, nowhere else, is that right? Is it a server-wide setting no matter what? If it was not set either way at the time I instantiated the problematic vhost, would this be inherited by the vhost somehow?

Either way, I think I'll need to reinstall everything and see if it makes a difference.
