When I install SplashGate, the 'Make Page Splashable' widget is available when editing any page.
Under Settings, SplashGate allows me to set the splashable page with a radio button. However, I do not see any of the other options described nor do I actually get a splash page when I visit my test site. I only noticed that I should have one by looking at the screenshot in the /splashgate directory of the management page.
My installation is not in the root www of my site if that makes a difference.
Could it be a problem with my theme? Do I have to manually edit any of the files to activate?
