Alright, so I think I just fixed the issue with my blog. Apparently it wasn't 3.2's fault, it was a Chrome extension called Troll Emoticons. I had disabled CloudFlare for my site and everything before I looked at the errors in Chrome's dev tools and figured it out.
So now it works, post titles appear and the Add New Post page works correctly. I'm still testing it a bit, there might be a cache still hanging on somewhere that I forgot to clear, but it seems to work at the moment.
It's a nice feeling.
