Plesk doesn't start after upgrade

[LordH]

After upgrade from 8.3.0 to 8.4.0 i couldn't start plesk. It gives me these error
> /etc/init.d/psa start
Starting xinetd service... done

At least I managed to get the PCP running again.

I discovered, that

/usr/local/psa/admin/conf/httpsd.conf

had only 1 byte. The error_log showed a port conflict (that's why I tried to check the port configured). I restored an old backup saved by PSA and httpsdctl could start the PSA server again.

The update routine obviously badly failed and Parallels yet found NO WAY to help their users.

Thank you so much! This was the reason why i couldn't start plesk. But i have to stop plesk with the command /etc/init.d/psa stop before, because status said "psa dead but subsys locked". So it didn't start before i stopped it.
And second thing was a MySQL-Error. In the config of MySQL (my.cnf) i used safe-updates and when i commented out everything worked fine for me.
