I notice that the plugin is not replacing the http to https when using a custom link via the builtin WordPress menu. I have a custom link to my home page. This link is internal, yet the plugin is not replacing the link.
Also, I am having trouble getting the SSL Errors to disappear from my page. I am attempting to use SSL on a single page. All elements on this page are being included via HTTPS thanks to your plugin. Only external file I am using is jQuery, which is hosted via HTTPS as well.
Are then any other items that could cause the issue? I am using latest version of Chrome as my browser. I assume your plugin modifies the code before output, so the browser should see everything as HTTPS initially.
Also, there is an ajax request on the page I am attempting to secure. Perhaps this could cause the issue?
