Hmm.. There are a lot of configs the installer sets up and creates. Unless you have a backup of everything some where trying to do a manual fix can be very difficult. If you don't have all your sites setup (or if they are easy to reinstall) my opinion is to do a fresh install of minimal OS and Sentora. This way all the configs will be set back to Sentora defaults.
From there, if you want to play around with it, you can take a snapshot (if on a rented VPS or virtual machine) or do a system backup so you can restore back to original if something happens again.
