I made a change a while back to how the blog creates content pages (which also posts to the forum, since they are one and the same), not realizing that I also had to change the page that makes a new forum post as well. Because normally I just made new blog posts, I never thought to check it. :( Bad developer, no cookie for you!
Anyway I fixed it. Sorry about that.
