I have 3 websites host on a single server, and only one of those website is using SSL. I bought, configured and installed a GoDaddy certificate and it is working fine on all browsers (Chrome, FF, Safari, IE) except Opera which is issuing a warning as described in my question. When I click on details, the hostname showing up is one of the others websites running on the server.
I've read some post about it on here, especially about SNI but can't really understand what I have to do and if this is easily fixable. I am running a Debian Lenny with Apache2 everything up to date.
