I have just finished an ecommerce wordpress website & have installed a SSL certificate on the whole site. It works fine except on my Vista PC when using IE9 which gives a security risk warning & recommends leaving the site. When I click on the certificate information, my SSL isn't listed but a parallel plesk panels invalid certificate is displayed.
When I run IE9 on my windows 8 & 7 laptops it is fine; if I didn't have a vista machine I would never know of the problem!
I want to resolve it because no one using vista & IE9 will want to use the site.
Has anyone experience this issue?
