Oops, an unexpected error occured (when logged in and visiting home page)

It’s been fixed for me. The “Recent activity” section now appears as normal (albeit slightly slower than the other ones). Didn’t do anything on my end. Just opened the page and it was there. I also refreshed a couple of times and there was no problem.

On my iPad and MacBook Air: After five or so seconds, Recent notebooks shows up correctly. Recent activity stays grey, and end up in Oops… after another five seconds.
