How can I fix a Facebook block glitch?

[Gabby]

Awhile ago one of my Facebook friends deactivated her account. For some reason I accidentally blocked her I think while her account was still deactivated but then I immediately unblocked her. That was at least six months ago. Now I cannot find her on Facebook. It's like I am blocked from her or she is blocked from me, but she is not on my block list. I don't know what is going on. Is it possible that Facebook has us blocked from each other even though she is not on my block list and I not on hers? Could it have been because I accidentally blocked her while her account was deactivated? How can I fix this?
She actually reactivated her account about five months ago so really what I am worried about is if Facebook glitched when I accidentally blocked her but then unblocked her while her account was deactivated. In other words, I'm wondering if Facebook still thinks that I have her blocked. But she isn't on my block list. And I have already sent in several reports and they haven't gotten back to me.

FACEBOOK won't block you both, but u can tell her to reactivate her account as u have accidentally made an error and u want to check about that.

Facebook wont block. I think it is a bug, File a report to Facebook.
