I had the same errors. Additionally, I had several other problems in the last two weeks. Since I could still use CB´s functions, there was just no need to mention it.
For example, a pretty raw front page, just black on white, with the articles in a different format than usual. On top of the page is not "Celticsblog", instead I get "Google advanced tracking modul".
Sometimes I click on a thread, and it opens a completely different thread, which is even not in the "latest topic" list, so I did not just click on the wrong thread.
It happened that I logged in, and had a message on the front page that I could now write an article for Celticsblog. That was clearly a "writer`s only" function.
Oh, and I can`t read the last 1-2 comments of every article. It shows 7 comments, for example, but I can only read 5.
All minor things, but I thought I should mention it, now that I read this thread.
