Assets/_SCRIPTS/Login.cs(26,33): error CS1525: Unexpected symbol `StartCoroutine' - Loging script

ERROR

When I run the game and want to login it will give me error:
could not locate page but when you go there, you see it work…

So here is C# code and Php code:

C#

using UnityEngine;
using System.Collections;

public class Login : MonoBehaviour {

	string loginURL = "http://www.disease.g6.cz/game/login.php";

	string userName = "";
	string passWord = "";
	string problem = "";

	void OnGUI() {
		GUI.Window (0, new Rect (Screen.width / 4, Screen.height / 4, Screen.width / 2, Screen.height / 2 - 70),
		            LoginWindow, "Login");

	}

	void LoginWindow( int windowID ) {
		GUI.Label (new Rect (140, 40, 130, 100), "--- Username ---");
		userName = GUI.TextField (new Rect (25, 60, 375, 30), userName);

		GUI.Label (new Rect (140, 92, 130, 100), "--- Password ---");
		passWord = GUI.TextField (new Rect (25, 115, 375, 30), passWord);

		if (GUI.Button (new Rect (20, 160, 175, 50), "Login"))
						StartCoroutine (handleLogin (userName, passWord));

		GUI.Label (new Rect (55, 222, 250, 100), problem);
	}


	IEnumerator handleLogin(string userNamez, string passWordz) {
		problem = "Checking username and password...";

		string login_URL = loginURL + "?username=" + userNamez + "&password=" + passWordz;

		WWW loginReader = new WWW (login_URL);
		yield return loginReader;

		if (loginReader != null) {
						problem = "Could not locate page";
				} else {
					if(loginReader.text == "right") {
				problem = "Logged in";
			} else {
				problem = "Invalid username or invalid password";
			}
				}
	}
}

Php

<?php
	$username = $_REQUEST["username"];
	$password = $_REQUEST["password"];
	
	include "sql_connect.php";
		md5($password);
		$query="SELECT * FROM users WHERE websiteName='$username' AND password='$password'";
		$result=mysql_query($query);

		$num=mysql_numrows($result);

		mysql_close();
	
	if($num > 0) {
	
		echo "right";
	}
	else {
		echo "wrong";
	}

?>

I have met the same problem.

and i suggest you modify

   if (GUI.Button (new Rect (20, 160, 175, 50), "Login"))
             StartCoroutine (handleLogin (userName, passWord));

to
if (GUI.Button (new Rect (20, 160, 175, 50), “Login”)){
StartCoroutine (handleLogin (userName, passWord));
}

have a try ?
