I updated to the latest version and later that night realized I couldn't login to the admin area. It took an hour for me to remember I'd updated the plugin that morning and I had to delete it from the server to gain access to the site again.
Now, whenever I try to re-install it or even roll back to an older version, my site times out and goes offline when I try to save the settings. In a nutshell, I can no longer use this plugin.
