Hello. My name is***** to JustAnswer. I'm reviewing your question now, and will post back with your reply momentarily.
What device are you using?
In order to help you, I need to know what operating system you have on your device. Windows Vista, Windows 7, 8.1, 10, or do you have a Mac?
What browser are you in or are you on the Facebook app itself?
What happens when you try to connect to your timeline?
What browser are you using? Firefox, Chrome, Internet Explorer etc?
Whatever browser you are using, log out of your facebook. Then open
a separate browser, sign into your facebook and hit your timeline from there.
Does it come up?
