[isshification]

so last year i decided not to let everyone comment or like my profile picture. i forget how i've done that but i manage not to let people click on my profile picture. Now i want to let people like and comment on my picture back again but i've no idea how to undo the settings i've made.

1.) go to your profile.
2.) click photos on the left hand under your profile picture
3.) click " profile pictures "
4.) You should see your name, then albums in blue above the photo collection
5.) click " albums "
6.) you should see " profile pictures " and any other albums you have uploaded. look at " profile pictures " dont click anything, but look under the album cover picture where it says how many photos are in the album, there should be a little gray figure that has a arrow that signals you can click it for more options
7.) click it, it should say, public, friends , only me, custom etc.
8.) click whichever one you want, friends or public to see your pictures (:
