Opera: Behave, or I’m going to delete you.
My Opera install decided to start randomly breaking my website. This is what my website looks like to all the other operas of the world. And this is what it looks like to mine: Um, No. I went through my theme and most of my plugins line-by-line before I figured out that it couldn’t possibly be anything but the browser, so I had to delete what few settings I have in it which fixed it.
