Running 3.4.2, installed on my development site, as soon as I activated I got server error 500. Unable to access the admin screen (because of error 500) so couldn't deactivate or uninstall - so I first deleted the plugin folder - still no go. Renamed the current theme hoping the default theme would kick in, but it didn't, still got error 500. Thought it might be .htaccess issue so renamed that but still couldn't access the site. It's only a dev sit so I ended up restoring from a backup. I would love to install this plugin as it's exactly what I need. Any ideas why this might be happening and what I can do to fix? If you like I can install on another 3.4.2 instance so you can see what's happening.
