Display Above Root Image with a controller on CI3-RC2

I told you to remove it because it's wrong regardless of the problem that you're having - get_instance() gets an instance of your controller, and you're calling it from that same controller's constructor, which in turn is the place where a lot of stuff is loaded, so it made sense that it could break something.

Thank you for let me kow that.

However I don't believe this is a browser issue. I try with three different browsers and there is no difference. As I mentioned before this not happens with CI3 previews version using the Session_native.php driver. It seems to be something on CI3-RC2 session improvements. Or a PHP bug inadvertently exposed.

I'm not saying it's a browser issue, I'm saying that's how a browser probably behaves.

Previous CI3-dev versions didn't enforce strict mode sessions, so that might explain it ... Either way, look at the request headers.
