I have a site that demands a SSL cert. The cert expired so I used your guide to generate a new certificate then followed the guide to use RapidSSL. Now when I try to start apache I get domain.bundle does not exist or is empty. So after getting that I copied the new certs into a file called domain.bundle and tried again to start apache. Now I see this: Restarting web server: apache2 failed! Anyone's help is appreciated. I really need to get this site up and running again ASAP.
