C# For loop in button to set gameObjects in array to active

I have multiple buttons in my scene which, when selected using oculus touch controllers with NewtonVR, the player teleports to and the button is set to inactive. When they then move to another button, I want the button to be set to active, but it doesn't work. The array contains the buttons which are all assigned in the inspector. Here is my code:

 public class PlayerMoveTo : MonoBehaviour {
 
     public GameObject player;
     GameObject parent;
     public GameObject[] previousLocation;
 
     private void Start()
     {
         previousLocation = new GameObject[7];
     }
     public void MoveTo()
     {
         parent = transform.parent.gameObject;
         player.transform.position = parent.transform.position;
         gameObject.SetActive(false);
 
         foreach (GameObject i in previousLocation)
         {
             i.SetActive(true);
         }
     }
 }

I originally had a series of if/else if doing the same thing minus the array but that's poor coding standard and annoying to add more buttons. I also tried for(int i = 0; i < previousLocation.Length; i++) but this didn't work either. What am I missing?
