Tumblr is bein a fucking BITCH

For starters, when I try to got to the default page (www.tumblr.com/dashboard), one of two things happens.
I either get this:

OR I get on my dash - but when I attempt to post, it won't let me. I don't even get an error message or anything. It just doesn't post, the unsubmitted post just SITS there. I click the "Post" button, nothing happens. Sometimes, it will load for awhile, as if it will post, but then the loading bar disappears and nothing happens. And when I refresh the page, I get the same error screen as posted above.
I'm able to like posts made by other people. But I can't make my own posts, or reblog someone else's post.
Before anyone says it, I have checked Isitdownrightnow.com, and it says Tumblr is up and running for everyone else. And no, this definitely hasn't got anything to do with Net Neutrality - it won't be voted on until Dec. 14, and even then there's no guarantee it will die. Still keep spreading the word though.

Anywho, I'm done bitching. Tumblr, please get your shit back together. Or if one of y'all knows what this means and how to fix it myself, I'd appreciate it. I might try the classic "turn off and on again" strategy with the Wi-Fi.

EDIT: I was wrong, I can't like posts - it looked like I liked a post, but I managed to access my page of liked posts, and the last one it says I liked I liked hours ago.
Also, I turned my Wi-fi on and off again, didn't do anything - maybe I should try turning the router on and off again??? Or maybe I should just wait for the problem to clear itself up. I just don't know.

EDIT 2: Speaking of shit sorting itself out, I just successfully liked a post. Imma try to make a post now.

WE'RE BACK IN BUSINESS BITCHES
