I've been working in a character during my free time, and I came to the point where I decided to Rig it using rigify. Everything went fine.. Until I tried bending the legs. Instead of bending like a normal character's legs would bend, the characters legs bent in the opposite Direction. I know that other people have come across this problem before, but there doesn't seem to be any IK constraints on any of the bones.
Nevermind, I found the IK bone on one of the hidden layers. :D
For anyone else with the same problem, the IK bones are on the second to panel in the layers area in the armature panel in properties
