Killed my website

I tried to delete all plugin data using the delete/uninstall option in plugin settings menu (I think that’s what it is called, not sure as I don’t have it anymore) and as soon as I clicked the button my site went blank, just a white page was displayed. Couldn’t get to the wp-admin menu of course and the only solution was to delete the plugin folder via FTP. Be very, very careful and think twice before you install this little gem.
