If you see an invitation to be a Tester for 'Srizon Album' accept it.
If you've already did that but still not working then we're facing an unknown problem or you denied some of the permission you were prompted with.
If you haven't received an invitation then I may have send the invitation to a wrong username. In that case share your username or profile link so that I can try adding you.
Note: Facebook isn't giving photo permission at this moment to live apps of this type. That's why I have to keep it in development mode and add the users of this plugin as a Tester.
It states this when I do it. "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."
