Opening the dashboard only displays the default apache page, reinstalling quickbox does nothing

I was installing other things on my server and had to install nginx. I think that is what ultimately screwed apache up. Now none of the dashboard pages work and the main quickbox dashboard is the default apache page. I tried reinstalling and it’s still the same. All previously installed services are still running, just not web accessible. Any simple way of fixing this without having to reinstall the OS? This would be the 3rd time I’ve had to reinstall the OS after getting everything just right because I end up doing something that messes up dashboard access. Should I be creating partition image backups?
