Yes, you have to be root to do this. But DON'T DO THIS if you are
still using VNC as that will start up yet another process of the
website and is likely to just make it worse as they both try to
contend for the same ports. There is never a need to do both of
these.
All I could do is simply repeat what you have already done which is to
shut it down with vncserver -kill :1 (this :1 assumes that this is the
assigned display port stated when vncserver was original run, you can
also see it in the command line of the XTightvnc command line) and
then start it back up with vncserver. After that the problem is
almost certainly with something in the image and so you will have to
fix it from there.
So I just tried this and am not able to get into the image via VNC, so
something is badly messed up with the image. At that point the only
choice is to recover from backup. One piece of information you
perhaps did not have is that you can find local backups on the system
under /var/cache/rsnapshot/*/localhost/home/website/ . It just so
happens that under
/var/cache/rsnapshot/daily.0/localhost/home/website/website/ (today's backup)
there were copies made at about 15:00 UTC on the 24th. I copied those
over the current copies (~website/website/squeaksite.image and
squeaksite.changes) and started vncserver back up and the site is now
running again.

Chris Cunnington contacted me indicating that the SOB felt that the
website needed some changes that could not be made through the web
interface, had had no luck contacting Janko, and asked me to provide
access.
So I backed up the old VNC password and assigned a new one (I did not
know, or at least remember the old password). The site was not
currently running under VNC so I stopped it after verifying that the
image had been saved relatively recently and restarted it under VNC.
The new password has been sent to Chris Cunnington and Bert
Freudenberg. Please contact them if you feel you should have access
to the Squeak process underlying www.squeak.org.
