The update to Post From Site on Sept 2nd was not supposed to go out as an actual update. If you downloaded it, it likely broke your site. What you should do is disable the plugin, and/or revert to 2.0.3. The plugin directory now shows the correct version.
As of Sept 5, 2.0.3 is the most current stable version.
If you’re interested in why this happened, my readme.txt – the file the directory uses to know where to find the current version of a plugin – was malformed according to expected format. So it didn’t know where to look, and grabbed the in-development version, which was a non-working screenshot of my code, basically.
