I recently upgraded to WordPress 1.5, which has some nice added features. I also tried installing the new Spam Karma 2, which unfortunately sucks. I’m sure if it’s working correctly, it’s quite helpful, but after monkeying around with permissions, directory locations, and plugin settings, it still couldn’t give me the options/admin page without a ton of errors. It was also blocking every single comment that people tried posting. I decided to scrap it, and I was able to rescue some of the real comments that were blocked on my last post. I’m going to try relying on WordPress’ own built-in blacklisting and moderation tools for now. Let me know if you continue to run into problems trying to comment.
