I re-named the install directory and was able to login as admin, it's showing the correct version but I'm unsure about if the database was updated correctly.
The front-end does not work at all:

I have flushed the cache, re-uploaded the classic theme.
Nothing shown in the error logs and unsure how to troubleshoot next.
Edit: All admin pages work perfectly and I can't see any missing data. So it appears to be a front-end issue.
