Ever since I upgraded to 2.9.1 (at least that's when I think the problem started) every comment being made on my site automatically goes to "Spam". I turned off "hold comments for moderation" but everything still goes to spam! The only way I can stop this from happening is to turn off Akismet, which seems to fix the problem.
I saw an older post from about 4 months ago that says there is a bug in reCAPTCHA that could cause this, but reCAPTCHA has been working fine for me this whole time.
Any ideas what could be causing this?
