Need help removing a self signed ssl cert and installing a commercial cert. I think I am having issues getting the self signed cert deleted and the new one loaded in its place.

I used the following wiki to delete the self signed cert:
SSL Certificate Problems - Zimbra :: Wiki

and the following wiki to request and install the new cert:
Commercial Certificates - Zimbra :: Wiki

I got the server restarted (after fixing a keystore password issue - new cert did not use 'zimbra' as the password). However, the imap and ssl services never responded. I restored the old self signed certs and the services back to running under the old cert.

So the question is .. What did I miss or where might I look for 'error messages' that might give a clue?
