I committed to the beta for programmers.stackexchange.com. I can sign in but am unable to a post a question.
I keep getting redirected to the "Oops! Something Bad Happened!" page.
Earlier I posted something on the meta page but am unable now.
Edit: Looks fixed. Thanks for the quick response, Jeff (and or whoever else was responsible). :)
I'm getting this as well. I propose Hijacking http://meta.programmers.stackexchange.com/questions/42/what-should-the-404-image-be for internal discussion (since we can't post new questions).
It looks like it's been down for a good 8 hours (since that's when the last new question was asked).
