not being able to log into Facebook could be seen as a good thing.
Delete the Facebook app, including the preferences, re-download and try again.
After the latest update to my macbook High Sierra 10.13.3, my laptop has prompted me to relogin to FaceTime before using it. This task has grown tedious after 2 weeks of trying to login and the login not working. The same error message is displayed every time, "An error occured during activation. Try again." Has anyone ran into this or can help me? In order to be part of Apple Support for help with issues I have to be a member which apparently is a benefit I don't have, and a benefit I need to pay for... Any help would be appreciated!
