Google announced that web hosting in Google Drive will be deprecated. You can continue to use this feature (and this plugin) until August 31st, 2016, but after that, googledrive.com/host/ID will no longer work. Note that due to this fact, this plugin will no longer be supported and further developed after 01.09.2016.
