I’ve setup a site for a client with an SSL Certificate. Everything works fine in Chrome, Firefox, Opera, and Safari. All of them check out, and all of them have the locked symbols, green success messages, and the like. That’s all fine and dandy until I get to Mobile browsers, and Internet Explorer (6 specifically, and others).

I’m using the following specs:
- PHP 5
- WordPress 3.+ (Latest)
I’ve done the following:
- Used ob_start() to enclose all the contents of the pages, and forced everything to have an HTTPS prefix.
- Downloaded Fiddler to take a peak at the HTTP requests, but I can’t get a good read on what exactly is wrong.
- I downloaded a couple plugins to force SSL on the site. I also changed the SiteURL to include https://.
