SpongeWise Flashcard Clipper

I cant save anything. Saving content for later is the entire function of this app. It is not functional. The only sign in option is through facebook and it doesnt work. facebook gives this error:App Not Setup: This app is still in development mode, and you don't have access to it. Switch to a registered test user or ask an app admin for permissions.

I use SpongeWise and the Chrome extension pretty much everyday when I come across something I want to learn.
