Installed this plugin and got white screen in entire admin area (which had been working before). Narrowed it down to a conflict w/Web Ninja Google Analytics plugin. Sure enough getting rid of that plugin solved the problem.
From debug mode it looked like the problem was with the GA plugin, not this plugin (the page literally FILLED with errors from GA plugin).
I'm raising the topic only in case someone with that plugin installed (or who hopes to use both) ends up running into that problem, so this may save them some time. In my case, I'm just going to find another analytics plugin.
