Ok I have an ecommerce site, the front end is working fine but the back end (admin panel) or checkout pages (https) are erroring.
I run centos 6, nginx, redis cache, php-fpm, maria db
It was working fine until all orders stopped a few weeks ago. The only thing I can think of is that we recently added a new domain on there and changed the https dedicated IP address to use for the new domain, the guy who did it was positive that we nginx did not need a dedicated IP for https? I don't know if this is the cause but I need a very experienced sys admin who can easily find and sort the issue urgently please. You must have at least 10 prior feedbacks.
