How to fix Photon Script

So, I was trying to add a server-sided script, and I don’t really know how to fix it.

I get the error when I try it:

RPC method ‘EnableObjectRPC()’ not found on object with PhotonView 1. Implement as non-static. Apply [PunRPC]. Components on children are not found. Return type must be void or IEnumerator (if you enable RunRpcCoroutines). RPCs are a one-way message.

If anybody knows how to fix this, any help would be greatly appreciated.

Here’s the script:

using UnityEngine;
using Photon.Pun;

public class EnableServersided : MonoBehaviourPun
{
    public GameObject objectToEnable;
    public PhotonView photonView;

    void OnTriggerEnter(Collider other)
    {
        if (photonView.IsMine && other.CompareTag("HandTag"))
        {
            Debug.Log("Trigger entered by local player with HandTag. Calling EnableObjectRPC...");
            photonView.RPC("EnableObjectRPC", RpcTarget.All);
        }
    }

    [PunRPC]
    private void EnableObjectRPC()
    {
        Debug.Log("RPC received. Enabling object...");
        if (objectToEnable != null)
        {
            objectToEnable.SetActive(true);
            Debug.Log("Object enabled for all players.");
        }
        else
        {
            Debug.LogError("objectToEnable is not assigned!");
        }
    }
}
