How do I make Facebook private except to friends (2013)?

[Roy Lucier]

Facebook has changed the way you do this, and I am unable to change my settings so that only my friends can see my posts. On my wall, using a fake account, I was able to see past posts even from two weeks ago. I have a stalker of an ex wife and need to change this. Can someone help me please?

[Hi !]

On the top right corner of the Facebook page, there are options, like home, logout, etc
Among those buttons there's a lock sign. That sign will be next to your home button.
Click that lock button
You will see three options
Click the one which says "who can see my stuff"
Click that and change your setting as per your requirements !

you need to use the "limit past posts" function which changes all public status updates to "friends only"
