Unity C# transform.LookAt rotating on wrong axis - unity3d

Question

Im making the basic foundations of an RPG game. Its point and click, using a navmesh. I have set up the player to move to an enemy and attack when in range. The problem i am having is that when the player reaches the enemy (or the chest/interactable) it rotates on the x axis. Im assuming its something to do with the lookAt function using the pivot point of the target object, but i cannot find a solution. Any help directing me to a solution would be amazing. I have scoured sites, forums and the Unity API for a couple of days now. Im sure its something simple, i just cant seem to see it.
Much love
