My Facebook location services aren't working on my iPhone 4S?

I'm trying to upload a video to my Facebook page but I click on the status thing that lets you do this and when I click upload existing it come up with a page saying that my location services aren't turned on. But they are. I've turned them off and on, I've uninstalled it and reinstalled it so that it comes up with a thing asking if Facebook is allowed to use my location, I click yes but it still won't work. What's wrong, how do I fix it!

Sounds Like a Error with Facebook you Can't Fix it Only Facebook Can Please Contact Facebook at the Help Center and Report the Problem to them

You went to settings and selected "location services" and made sure Facebook was "on"? If so, it seems like a Facebook error.
