Sieve for roundcube. Nothing happening after install

[trogvar]

I’ve installed Sieve using script from upgrade/manual folder.

bash install_sieve.sh

I see it in logs:

Jan 12 16:04:31 master: Info: Dovecot v2.3.13 (89f716dc2) starting up for imap, pop3, sieve (core dumps disabled)

But I can’t see any changes in webmail rouncube interface. Can’t see filters option in Settings. Tried to restart everything, nothing helped.
What should I do else?

Thanks!

Had to manually add plugin name here:

/etc/roundcube/config.inc.php

$config['plugins'] = array('password', 'newmail_notifier', 'zipdownload', 'archive', 'managesieve');

And it appeared in Webmail.
