I have a fresh install of WordPress 2.9.2 running the P2 theme at gravepost.com. I've started getting it set up, and like the potential the theme has, but there's one major problem. Every 15 seconds, WordPress (or P2) duplicates all the posts on the site, refreshing them. After being gone from the page for a few minutes, I can click back to its tab and see multiple copies of the same "Test" post. This also happened with the original "Hello, World" post, which has since been deleted.
I have no plug-ins running, and I'm using the latest versions of both P2 and WordPress. Is there a solution in sight?
