I had to re-set up my Zimbra-Server from scratch after a hardware-crash.
Everything works fine again, except one problem: I have a commercially signed certificate (which i bought, after i set up the server the first time about a year ago) and now i want to use it for my new installation. But i cannot install it via the admin-interface: It says something like "XXXXX Error: Unmatching certificate ...."
The servername, email-domain, etc. are all unchanged since last setup.
what should i do to be able to use ist again on my fresh installation?
