Re: Blank page while installing
w00tw00t.at.ISC.SANS.DFind is a different problem altogether. Looks like someone is scanning the server for vulnerabilities.
If you have root on the server you should be able to resolve this. It might be in a php_error.log or maybe it is in an apache access or error log, but those lines there are not the ones you want.
I would determine the IP address you’re visiting from, then grep through the logs for that IP and you should see the error.
