Server config causing CSRF triggers

OK, I finally found the source of the incompatibility with CodeIgniter's CSRF. In php.ini if

Code:

suhosin.cookie.encrypt = On

is found then it causes CSRF in CI to kick back a 403 on ajax requests and probably others, but I noticed it on the axaj calls. There are two solutions.

Unsafe
Comment out

Code:

suhosin.cookie.encrypt = On

in php.ini

Safe
Create the line

Code:

suhosin.cookie.plainlist = [insert csrf cookie name from config.php]

in php.ini with no quotes around the cookie name. Any other cookies should be separated by a comma.
