I've had real problems getting ssl to work on my website: http://www.reallysimpleseo.com, which I think may be a combination of the theme and plugins. So I stripped a page right down with no text or images to try and still no luck. https://www.reallysimpleseo.com/members/ssl-test. I also got https://www.reallysimpleseo.com/members/join-e-learning-centre which I'm working on as the main secure page.
I came across your plugin, installed and set it up and now the pages are more secure, but there is still something that is causing it to be insecure.
Any suggestions would be much appreciated.
