Plugin broken under PHP 5.3.5 on WordPress 3.2 and 3.2.1
Under PHP 5.3.5 my home page loop reports 404, blog won't show and dashboard "All Posts" to show Auto Saves and what I'm guessing are post revisions... Disabling the plug returns everything to normal.
I discovered this only because the site I just installed this on last week was kicked off it's shared server for excessive resource usage. I copied the site to my local environment which is PHP 5.3.x. I don't know definitively that this plugin was to blame for the excessive resource usage, but it's a reasonable place to start.
