Player gets stuck in air once attacked

I'm having a problem with my player when it gets attacked by my enemies. When it gets hit my player gets smacked up into the air then seems to be stuck floating above ground level by a few feet. I am also still stuck after respawning. Before I engage in combat my player stands and moves perfectly on the ground.

Here are some screen shots to demonstrate:

Does anyone have any ideas as to what the problem may be? I've tried moving the players and enemies controllers higher and lower, but no luck.

Thanks.

 

I could really do with any suggestions, need to have it working by tomorrow.

:cry:

 

I've noticed that when I un-play the game inside Unity I notice that the enemies capsule seems to enlarge and morph quickly, could there be some kind of real time error causing this?

 

eh, it's hard to say what's going on. When the player is stuck in the air.. are they stuck? as in no more movment, or just elevated. if so, you're probably somehow animating your capsule collider. maybe you've parented it to some bone or something else you shouldn't have.

it's easy to see what's going on.
Play it in the editor, when the character is stuck pause the game and look in your editor and find your character controller. you should see it outlined in relation to your character object.
