500 - Internal Server Error

When i try to login into Parallels Plesk Panel, i get the following error: "500 - Internal Server Error". What should i do?

There can be a lot of possible reasons of this issue. First of all - try to find reason in /var/log/sw-cp-server/error_log

This is what i found:
2010-06-16 11:00:04: (mod_fastcgi.c.2476) unexpected end-of-file (perhaps the fastcgi process died): pid: 24370 socket: unix:/usr/local/psa/tmp/sw-engine.sock-0
2010-06-16 11:00:04: (mod_fastcgi.c.3259) response not received, request sent: 1082 on socket: unix:/usr/local/psa/tmp/sw-engine.sock-0 for /login_up.php3 , closing connection

Any ideas?

Is it Virtuozzo container based Plesk? Very often this problem related to lack of container's Virtuozzo resources. Make sure that you haven't failcounters with something like:

# awk '$NF > 0 {print}' /proc/user_beancounters

Also make sure that you have enough free disk space there.

Yeah, i guess it's virtuozzo. I am newbie, so i don't understand what you mean by saying failcounters. And my server has enough free disk space (approx. 20GB). The problem is that my Plesk Panel was working correctly before when one day it showed "500 - Internal Server Error". I did nothing to server. Maybe there were any auto-updates that ruined something??

Read carefully Virtuozzo documentation about resources management for containers.

What will happen if i run this command /usr/local/psa/admin/sbin/autoinstaller ? Will all my files and databases be deleted?

You will just perform upgrade to latest available version with autoinstaller.

Will i lose any files after update?

No. Create full backup of your server if you afraid.
