Hi. I've used the howto install horde5 on Debian Jessie and ISPConfig3 and have encountered a problem. When I click on the edit symbol on an addressbook, I get a message from my browser that "Safari can't open the page "https://designrus.dk/horde/turba/addressbook/edit.php?...." It does not happen with the calendar or other modules. I can add adresses and all through activesync. Any ideas?
