All logs under "MONITOR" in ISPC are dated: "Data from: 2010-11-28 05:40" so they are not updating at all. So, no new content is provided to find errors that way.
Unfortunately, I won't be able to get onto SSH for another hour to open up /var/log/ispconfig/ files. Stay tuned on that one.
ISPC3 on Debian! It's great!
