More than one ADMIN!
After several training courses around Australia, I noticed an upward trend of Council's and local gov losing control of their Facebook Pages.
FAKE ACCOUNTS: Facebook makes sure that in most cases People Profiles manage Business Pages and that the Profile MUST be a real person. It is in the T&C! They suspend both (profile and pages) and ask for a birth certificate if they suspect a fake account. This is a common problem on Facebook. Do not create fake accounts to log in and out of Facebook because your team WILL trigger a Facebook suspension.
Make sure you go to Settings tab and add more than one Admin. Not Editor, Admin.
