This is first post following DreamHost one-click upgrade to WordPress 2.0.5. Consequently, this would be considered a test post.
It seems some people are having a Server 500 Error or something like that, and they have issued a plug-in to fix it. Kind of hard to install and activate a plug-in if all you get when you try to get the blog is Server 500 Error message, but apparently it can be done by command line, if a person knows how to get to command line on their blog server and use it effectively.
