SSL and https problems
 

My site is hosted as domain.com and the SSL certificate was issued as domain.com. When www.domain.com is used a warning appears that certificate was issued for another website so I added a 301 perm redirect to sent the www.domain.com to domain.com. This part appears to work.

However, now anytime I go to a secure page (domain.com or www.domain.com) an ugly warning appears-- what else do I need to do?

A 301 redirect won't do it, you need to use mod_rewrite. Have a look at #10 on this thread:

And FYI, you really should be using www.domain.com for both http and https. I'd see about getting the ssl cert re-issued.
