How do you see notifications from someone after you've unblocked them on Facebook?

[Erica]

A while back I blocked this girl that used to be my best friend, now we're speaking again, and we're friends on Facebook (which automatically unblocks her, correct?) I'm not seeing anywhere that it says she's blocked, but it doesn't notify me when she's commented on something of mine, and our messages aren't going through to one another. What's the problem, and how might I fix it?

Thanks!
She isn't on the block list, which is why I don't understand..

you have to go under account > privacy settings > block lists (at bottom of page) then unblock them.

they should start popping back up or just go to their page
