csrf error

The action you have requested is not allowed.

The errors comes from system/libraries/Security.php, you can find it there if you search this error message.
Errors is throwed when csrf token is invalid.

1. Try to changing the weird the that use gave:

Code:

$config['csrf_cookie_name'] = 'hgjhg@#ouppou';

2. Once I was given a server with Session disabled, I could not use Session until hosting company enable it. Maybe the same case with Cookies, it is disabled on server (I don't have much experience using Cookies)
