Can someone explain me why SSLStaplingCache was removed from the vhost.conf.master template ? If this is not available with SSLStapling enabled Apache will not restart!

@pdreissen Because it was moved to install/tpl/apache_ispconfig.conf.master there is no need to have this directive repeated several times in vhosts files.

Is this template used when updating the controlpanel ? I don't think so since after an update my vhosts (which changed configuration) where all broken because of a missing SSLStaplingCache so something needs to change when updating an instance.

@pdreissen Maybe you selected n when it asked for reconfiguring apache.

@pdreissen Just add these lines to file /etc/apache2/sites-enabled/apache_ispconfig.conf

<IfModule mod_ssl.c>
        SSLStaplingCache shmcb:/var/run/ocsp(128000)
</IfModule>

That's my point, that config file isn't available on anything else as the controlpanel. I'm running multi server, so in a single server this is viable on multi not!

Update: forget above it is available, however something is wrong with the update process as it doesn't seem to be added. Reconfiguring apache isn't a question afaik in the upgrade process, but reconfigure services is, that is always answered with yes in my case (autoinstall.ini).

Update2: It seems it is working i did an manual update on one of the nodes and the ispconfig.conf has been changed accordingly. Will check if something is wrong with autoinstall.ini

Update3: It was all down to a misconfigured autoinstall.ini. Thanks for your response, all is working as expected!
