SSL issue. Force SSL not working.

Major SSL issue.

I'm having an issue with SSL on my server. Basically, I am unable to "force SSL" on my server.

Case 1: In WooCommerce when I click "force SSL" on the "checkout" tab. If I go to the checkout page I get sent into a redirect loop

Case 2: Try to go to a regular page via https e.g. https://www(dot)herobureau(dot)com . The page displays without displaying insecure elements.Key formatting elements are lost. ie the page looks jumbled.If I then use "WordPress HTTPS" plugin to try and "force SSL" "secure all elements on the page" it does not work and has no effect. I have tried using iThemes Better Wp Security and have the same issue.

I have a presentation tomorrow and need this working ASAP. Please help.
