WordPress 2.0 Anomalies

I’ve installed WordPress 2.0 with the one-click option on Dreamhost. I’ve also enabled the AdSenseDeluxe plugin. Everything seemed to be working fine (over a week) until today. After adding several more posts last night in various categories WordPress is displaying some weirdness.

First, the adsense ads only display on the first post, not all posts as before. I’ve checked the AdSenseDeluxe settings and everything is correct. I’ve found that if I deactivate the plugin and then reactivate it the adsense shows correctly for one view and then disappears on subsequent page views. Also, the content relevance goes away and ads are shown that have nothing to do with my content.

Second, when I click on a category to display posts within that category WordPress displays the “Sorry, no posts found” message even though there are many posts. If I go into Manage Posts and open one of the posts in that category and then save it all of the posts will show again. But, then another category will throw a message saying that no posts can be found.

Any idea what could be causing this? The website is vampiregenre.com if that helps.
