Login problems - 500 error message

[BZDprint]

Hey,

I hope someone is able to help please? Every day when I try to login to Plesk I keep getting a 500 error message. Please find this below.

ERROR: SWKeyExFatalError
error: Cannot open file

0: common_func.php3:4536
of_get_key_by_product(string 'plesk-unix')

1: common_func.php3:4536
getPleskKey()

2: common_func.php3:4615
getKeyProp(string 'demo')

3: auth.php3:48

But when I run the command below:

cd /etc/sw/
chown psaadm.swkey-data keys -R
/etc/rc.d/init.d/psa restart

It fixes the problem until the next day and I have to run the command again. Do you know what the problem might be please?

Thanks

Make sure that /etc/sw/keys/registry.xml has psaadm owner but not root.
Is it Plesk installed to Virtuozzo container? If yes - is it Debian container?
