Just to clarify … it is considered customization to get a piece of the theme (the slider that comes with the theme’s Avia framework) to work properly?
Really Simple SSL actually broke the site worse, it looked horrible after using the plugin, AND did not take care of the insecure issues – the site still showed mixed content. So I disabled the plugin and returned the site to at least looking good on http.
I am also not able to get the theme header to accept an https version of the logo (same with the other image you noted). It will only show the logo image, whether viewing http or https, when the image itself is the http version.
Other suggestions?
