This is an intermittment problem in that some people can access my ecommerce site, place order etc and others get a security warning that the connection is untrusted. This has only started happening after my website developers setup an SSL certificate for me but they have double checked its setup and can find no problems and my site seems to work fine in FF for them My site works off xcart and the xcart people have also tried to replicate the problem but cant seem to find anything wrong with my site working fine in FF when they access it Despite this when I try to access my site in FF and several other people Ive asked to check it as well as several customers today we all get the same security warning
