Why am I seeing Registration required page even though I am registered?

If you already have a NinjaPoster account, and when you open the extension and see the registration required page, that means you are switched into a different Facebook profile or page on Facebook.

NinjaPoster is connected to a specific Facebook ID for profile or page. So it will only start the monitor if that specific profile or page is currently logged in and switched into in the same browser.

If you switch into another profile or page and start the monitor, it will show you this error.

To fix it,

Close this extension monitor page, switch into the right profile on Facebook and then start the extension monitor again.

That should fix it.
