Plesk Frontend Internal Server Error after Upgrading to 9.2.1

[M:ke]

Hello.

I got an Internal Server Error after SUCCESSFUL upgrade.

# tail -f /var/log/sw-cp-server/error_log

2009-06-17 19:52:23: (mod_fastcgi.c.893) bind failed for: unix:/usr/local/psa/tmp/sw-engine.sock-0 Permission denied
2009-06-17 19:52:23: (mod_fastcgi.c.1105) [ERROR]: spawning fcgi failed.

Solution: You have to chmod the directory.

# chmod g+w /usr/local/psa/tmp/

That works for me - for now.
