Hi,
there were two blue radio buttons that said ‘activate’ and ‘deactivate’. When I first activated the plugin, I noticed that the features were greyed out and I couldn’t work on the site. So I went to click the button to ‘deactivate’ the plugin and basically the site was gone. I tried to restore it, but because someone else built it, I don’t know if they had a backup. I then uninstalled the maintenance plugin and still no sign of the original site.
