App Engine Authentication Error

I have an app hosted by google app engine, and I am having trouble with authentication.

When I login using my admin account and try to access the admin page or members pages, I just get a blank screen. I can login, and the member开发者_如何学Cs only menu shows when I login, but I just can't see any data from the members pages.

I'm not really sure where I should start checking? My app is registered with my google apps account and I am using the only admin login that is there.

Any suggestions would be appreciated.

It sounds like you're running into the Google Apps vs Google Accounts issue. If you have a Google Apps account listed as an administrator on an app that accepts any Google account for authentication, it won't be recognized as an administrator. You need to create a regular Google account (such as a gmail address) and use that as an admin in your app.
