Application.LoadLevel() has been deprecated since (I think) 5.2. You use SceneManager now so change your code to the following.

using System.Collections; 
using System.Collections.Generic; 
using UnityEngine;
using UnityEngine.SceneManagement;

public class GameManager : MonoBehaviour 
{
     public static int currentScore;
     public static int highScore;
     public static int currentLevel= 0;
     public static int unlockedLevel;

     public static void CompleteLevel()
     {
          if (currentLevel < 2) {
              currentLevel++;
              SceneManager.LoadScene(currentLevel);
     } 
     else 
     {
         print ("you win");
     }
 }

Refer to the SceneManager documentation: C# Scripting API: SceneManager

Also, I forgot a bracket in my code so don’t forget to add a final bracket at the end!

The most preferred way to reload the current level is to actually remove the variable currentLevel and replace the function with SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);, although that’s a preference by me so that way I don’t have an extra variable and the code automatically works on any level application.

Surprised that you didn’t get a message about this, but you need to use the SceneManager class instead:
