We are having a really odd issue that I can not fix at all. I really need some help if you could.
The website www.cavendish-furniture-mobility.co.uk
is a wordpress\woocommerce website that works really great. However for the paypal plugin to work the checkout needs to have SSL forced. We have a SSL cert for the site which appears to be working fine BUT for some users it is taking up to 40 seconds for the page to load. The rest of the site is fast as it should be, but checkout is slow for some people.
This is what we know and have tried so far.....
1. If someone uses a device at one location and checkout is slow, they can take this same device to another internet connection and it works just fine, and vice versa. We have recreated this scenario more than once.
2. If I force SSL on the whole site then we get a redirect loop for everyone and the page wont load, however the back end does loads fine over ssl.
3. If i enable another theme, say twentyfourteen then everything loads fine over ssl for everyone, from any internet location.
Ok, so i think we have narrowed it down to the theme, but the theme creators are basically saying they have no idea and its not their problem.
I just don't understand how ssl works fine for some internet connections and doesn't for others.
The site is on a dedicated CentOS 6\WHM server.
Thank you for your time.
