i tested it , it doesn't have the problems v4 had !
Thanks a lot !

I faced few things though :
- Resetting the password with lostpassword didn't work for me, i edited it to be http:// and not https:// as it is in lostpassword.php.
It even ruins the password, even the old password stops working. What should i do ?
I think it is because lostpassword.php uses sha256 encryption and the login.php uses the $salt thing ?

- in accountdetails.php , you added the field ( current password ) to change the password, but even though you put the password it says " you must put your current password" , it doesn't  recognize it .

Thanks a lot simplecoin ! you are awesome !
