Not quite sure of version, it may be 2.9.1, but the problem I'm having is the reason I'm not sure of the version.
The instant I activated this plugin it coughed up a 500 Server Error. All of my site is now coughing up a 500 Server Error, including the admin area, so I can't actually do anything with the site, including deactivating the plugin. Areas of the site that don't run WordPress work normally.
I'm not sure what's going on because no one else seems to have had this problem and I can't think of a reason why this would happen only on my site.
