I have one scene which has many levels when i am playing and i want to restart this level i am loading the scene and activating the gameobject of the this level. But the scene restarts without activating the gameobject of that level. Here is my code

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using UnityEngine.SceneManagement;
public class PlayLevel : MonoBehaviour {

	// Use this for initialization
	GameObject Level;
	public GameObject Menus;
	Button button;
	void Start () 
	{
		button = GetComponent<Button> ();
		button.onClick.AddListener(delegate() {
			this.Restart();	
		});
		Level = GameObject.FindGameObjectWithTag ("Levels");
		Debug.Log (Level.name);
	}
	
	// Update is called once per frame
	void Update () {
	
	}
	public void Restart()
	{
		Time.timeScale = 1;
		SceneManager.LoadScene (SceneManager.GetActiveScene().name);
		Debug.Log (Level.name);
		Menus.SetActive (false);
		Level.gameObject.SetActive (true);
	}
}

Hi,
one thing can you confirm please, Debug.Log in restart is printing levelName or not? What i think you should activate level gameObject in start function. Because when ever you will reLoad scene. It will reset your all values and conditions. One thing you could do make public static bool reStart and set value true when you are pressing restart button. And in start check if (reStart == true) then activate level. and after activating on next line set bool to false. Public static bool keeps its value on reloading scene.

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using UnityEngine.SceneManagement;
public class PlayLevel : MonoBehaviour {

     // Use this for initialization
     GameObject Level;
     public GameObject Menus;
     Button button;
     void Start () 
     {
         button = GetComponent<Button> ();
         button.onClick.AddListener(delegate() {
             this.Restart();    
         });
         Level = GameObject.FindGameObjectWithTag ("Levels");
         Debug.Log (Level.name);

         Menus.SetActive (false);
         Level.gameObject.SetActive (true);
     }
     
     // Update is called once per frame
     void Update () {
     
     }
     public void Restart()
     {
         Time.timeScale = 1;
         SceneManager.LoadScene (SceneManager.GetActiveScene().name);
         
     }
 }

changes you made resets too when you reload a scene, activating that objects in start maybe solve your problem .
