Avoid this plugin. It SUCKS.
I installed an then ran it (Ver 2.6.1). The plugin put my system in maintenance mode then left it there without doing the update. Took me the several hours to figure out how to resolve the problem. If you want agravation, beat your head against a wall. It's less painful then this plug-in. I have no idea how this plugin got 4 stars. Judging by all the other negative comments, it does not deserve one!
