SSL Migration Failed

This may be our ignorance... I migrated hheonline.org from the old server using a Plesk 8 back up. /home/hheonline/ now contains:

ssl.cert
ssl.key

in the Web server config I imported both of those. We left the SSL enabled set to "default"
Protocols: all checked on
Client SSL Certificate: default
Client Certificate Depth: default
SSL log file: default

but if we try for a secure connection it says

Unable to verify the identity of Localhost.localhostdomain as a trusted site. Possible reasons: certificate authority not recognized; server misconfiguration; malicious pretender etc. If you chose to examine the certificate, it's obviously not loading the one we imported.

Status: 
Closed (fixed)
