Hi -- first tried to upload this plugin through the "search" screen for plugins in WordPress -- but when I activated it it made my Plugin screen disappear. (Whenever I clicked on Plugin it would just show a white screen.)
I went in through FileZilla and manually deleted it. The problem went away and my WP Plugin screen would resolve again.
I downloaded it again from this website, and manually unzipped and put it in the /plugin folder via FileZilla. Activated it again and...
same thing. White screen.
