I need to undo a facebook privacy setting...?

[Tony]

When playing around with my privacy settings, i marked someone unable to view my wall posts. When i tried to undo this setting, i was unable to. So, they still cannot see my wall posts and i do not know how to make it so that they can.

go to account--> privacy settings.
ther in the SHARING ON FACEBOOK part scroll down and click CUSTOMISE.
the first thing is what your problem lies rite, which is posts by you.
click the drop down box and select CUSTOMISE again.
there will be two options.
MAKE THIS VISIBLE TO and
HIDE THIS FROM.
if your friends name is over there then delete it...
if the problem is still there then try if your friends name is in BLOCK LIST. its just below in the privacy settings menu...... hope this helps....
