Question

I'm building a system in Unity that takes a register and login menu connected to a MySQL database through PHPMyAdmin, has users log in, then allows them to choose between playing two games. I've been getting this error since I linked the games and I can't figure out how to fix it. The register works fine, but it won't allow for log in.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using TMPro;


public class Login : MonoBehaviour
{
    public TMP_InputField nameField;
    public TMP_InputField passwordField;

    public Button submitButton;

    public void CallLogin()
    {
        StartCoroutine(LoginPlayer());
    }

    IEnumerator LoginPlayer()
    {
        WWWForm form = new WWWForm();
        form.AddField("name", nameField.text);
        form.AddField("password", passwordField.text);

        WWW www = new WWW("http://localhost/sqlconnect/login.php", form);
        yield return www;

        if (www.text[0] == '0')
        {
            dbmanager.username = nameField.text;
            dbmanager.score = int.Parse(www.text.Split('\t')[1]);
            UnityEngine.SceneManagement.SceneManager.LoadScene(0);
        }
        else
        {
            Debug.Log("User Login failed. Error #" + www.text);
        }
    }

    public void VerifyInputs()
    {
        submitButton.interactable = (nameField.text.Length >= 8 && passwordField.text.Length >= 8);
    }
}

I've been trying to figure out what happened for hours and need some extra insight, can anyone please help?
