Safari iOS (latest): white page with no content

[Simsnet (Glenn Sims)]

On Safari for iOS, whenever I visit a forum the page is all white, but on Chrome for iOS it loads normally.

My JavaScript and cookies are on. Any suggestions?

I first noticed this issue early Wednesday

You can repro this here on meta?

I am not having any issues viewing meta on my iPhone.

Slipped my mind completely!
The issue happens here.

Loads just fine on my iPhone, though I do get a mixed content warning. @tshenry can you fix that mixed content warning on Monday? This is a site we host.
