Question

I was in the process of "unliking" facebook pages that I had previously "liked." I found on my wall a list of upcoming events, that included an event from a page I had just "unliked." I clicked to block this event and somehow it blocked facebook completely. When I try to load facebook, I get a popup saying "This website, or elements thereof, are on the BlockSite blacklist (or not on the whitelist) and have not been loaded."
