I had previously linked my personal Twitter and Facebook accounts, then unlinked them.
Now I am trying to link them again, and no matter what I do, I get the following message:
"You're currently logged in to Facebook with a different account than the one you have linked to."
I have deleted the app within Facebook itself. At this point, I try to link the accounts again from
Settings->Apps->Facebook Connect. It then says "Continue as [my name]?" So clearly it detects that I'm logged in under my name. And yet at the end, I get this same error message.
Clearly, I am not logged in to Facebook with a different account. What happened?!
