Share To Facebook Missing From The Share Button In Charms

[deadwrong03]

I've had Windows 8 and never had this issue before but I have twitter, email and everything else but recently Facebook has gone missing from my options to share. After doing a little looking, I went to my People tile and saw that some how my facebook was no longer linked, I relinked it and got it back working in the people tile but when I try to share things Facebook is still not a option in there, ive restarted and still no luck. Is there any way to fix this?
