My sieve scripts don't get executed and when I enable debug logging I get following errors in the log:

Dovecot version is 2.4.5
Is there anything I can change in the permissions to get this working?
It has nothing to do with your sieve scripts not being executed though. You can ignore it, it's a debut message.
Sieve scripts are not normally executed by imap unless you try to use IMAPsieve or FILTER=SIEVE extensions.
