I had a problem with www.domain1 loading a cert from domain2 (non www for domain1 was fine) so I enabled Auto-Subdomain:www for domain1 and it fixed it. I access the ISPC admin pages with https://domain0.com:8080 all good, and webmail with https://domain0.com/webmail was working fine. Now going to https://domain0.com/webmail loads the cert from domain2, however admin panel https://domain0.com:8080 still loads correct cert. I have cleared browser cache, tried different browser and different PC Does that make sense?
