We transferred in a domain from another host, and while the site works fine on MOST machines, it doesn't for ourselves or our client. If we try to access the site using http://domain.com without the www., we can't access it as we get an error stating "Insecure connection". It continues to say it hasn't been configured properly and has an invalid security certificate. The hosts state that it's a local issue, I've tried flushing the DNS and clearing caches etc but no luck. Could anyone guide me through a possible solution for this?
