Cannot save Todo event on vTiger CRM 6.1

Question

I'm new to vtiger, I recently installed vTiger ver.6.1 and I noticed that whenever I tried to create a ToDo Event. nothing is saved.

Btw, I'm using MySQL.

I found this article here in Stack overflow:

Vtiger: I can't add a To Do event

but I think my problem is different from him. since he was using PostgreSQL and I'm using default.

another thing is, the OP mentioned a file:

TodoSave.php

but when I checked my vtiger folder. there is no TodoSave.php file

Hope someone could help me with this. Thanks in advance
