Hosts that insist on SSL by proxy, such as Network Solutions), will cause problems with WordPress and WooCommerce because they prevent PHP and the WordPress is_ssl() function from detecting if the page is being served over HTTPS. This causes a redirect loop.
In Network Solutions’ own words:
Network Solutions® uses a proxy SSL; this does not allow the use of server-side variables to detect HTTPS (secure). All server-side coding will always detect HTTP (non-secure), and for programs that attempt to redirect non-secure connections (http://) to a secure connection (https://) will result in an infinite loop and server error after 30 seconds.
Network Solutions have been aware of this limitation since 2007, so don’t expect a change in policy anytime soon.
There is no workaround within PHP (http://stackoverflow.com/questions/4686668/https-redirect-for-network-solutions). The only workaround is:
- Turn off the Force SSL settings within WooCommerce
Please note that we cannot officially support this non-standard setup.
