Regenerating Plesk files every day at around 6.15am ?? why

[AdamSa12]

Hello,

every day some config Plesk files are regenerated every day at 6.15am, eg file: /etc/apache2/plesk.conf.d/roundcube.conf

I know I shouldn't change content of this file, because it is generated manually, however I use Varnish Cache and I need have an access to webmail, so I need change something in /etc/apache2/plesk.conf.d/roundcube.conf

Why does Plesk regenerating this file? How can I stop doing this?

Plesk version: 12.0.18 Update #49 , the latest

Please advise
