I just got EduSec installed that went fine. I also got Database tables created successfully. But When I run the Login (after registration step) and give Login Id (Email) and Password. Then I get Captcha to enter. I have tried many times (more than 50 times) and Captcha keep on coming back with new one and I can not login. Why I am not able to login, I am sure captcha letters I am entering are right but Login screen keeps on coming back and I am not able to login.
