RC3 Installation Problem

[joximu]

It's difficult yet - some devs are working on the update script to also be able to update from rc2 to rc3 - but noone knows when it's finished.

You can try to update as described in the "small update howto", then do some comparison of configuration fles (mainly /etc/ispcp.conf - there are some new variables shich have to be inserted manually). I'd also enable php-debugging (error-log) to find other errors.
Most of the tpl files in /etc/ispcp/*/parts should also be updated...

With some engagement you should be able to do the update...
