yield WWW doesn't work

Question

Hi to everyone, I have a simple code that creates a new account on a database. The problem is that yield doesn't work and I really can't understand why. I attach my code below:

  /// <summary>
         /// This method prepares the informations to create a new account on database and starts a coroutine that adds the new account
         /// </summary>
         /// <returns></returns>
         public void CreateNewAccountOnDatabase()
         {            
             ....
 
             StartCoroutine(DBManager.Istance.CreateNewAccountOnDatabase(name, surname, identification, email, password));
         } // End CreateNewAccountOnDatabase

 /// <summary>
         /// This method creates a new account on database
         /// </summary>
         /// <returns></returns>
         public IEnumerator CreateNewAccountOnDatabase(string name, string surname, string identification, string email, string password)
         {
             WWWForm form = new WWWForm();
             form.AddField("Name", name);
             form.AddField("Surname", surname);
             form.AddField("Identification", identification);
             form.AddField("Email", email);
             form.AddField("Password", password);
             WWW createAccountWWW = new WWW(this.url, form);
             // Waiting for php to send something back to Unity
             yield return createAccountWWW;
             if (createAccountWWW.error != null)
             {
                 Debug.Log("Cannot Connect to Account Creation: " + createAccountWWW.error); // TODO
             }
             else
             {
                 string createAccountReturn = createAccountWWW.text;
                 if (string.Compare(createAccountReturn, "Success") == 0)
                 {
                     Debug.Log("Success: Account Created"); // TODO
                 }
             }
         } // End CreateNewAccountOnDatabase

Everything works fine...but the only problem is that after

 yield return createAccountWWW;

the program skips all remaining code and ends the method;

Thanks for all your help!!!

you need to put your WWWFrom form = new WWWForm(); and other form.addfields inside public void CreateNewAccountOnDatabase() and just change the arguments to just the forms like this.

     public void Login(string email, string password, string macAddress)
     {
 
         //encode
         byte[] bytesToEncode = Encoding.UTF8.GetBytes(email + ":" + password);
         string encodedText = Convert.ToBase64String(bytesToEncode);

         //form
         WWWForm form = new WWWForm();
         form.AddField("macAddress", macAddress);

         StartCoroutine(LoginCoroutine(form,encodedText));
     }



 IEnumerator LoginCoroutine(WWWForm form, string encodedText)
 {
     using (UnityWebRequest www = UnityWebRequest.Post(globalURL + UrlforAuthentication, form))
     {
         www.SetRequestHeader("Authorization", "Basic " + encodedText);
         yield return www.Send();

         if (www.isError)
         {
             Debug.Log(www.error);
         }
         else
         {
             userFunction.UserVoid(www.downloadHandler.text);
         }
     }
 }

This script is my log in script that has a server database.
