Upgrade problem

[eluser]Leonel Folmer[/eluser]
Hi everyone, I recently upgraded from version 1.7.3 to 2.0. I got this error:

An Error Was Encountered
In order to use the Session class you are required to set an encryption key in your config file.

I have a CRUD with sessions, but I do not want to use the Encryption Class. Also in my config.php file I have set like this:

Code:

$config['encryption_key'] = "";

Anyone know what this is? need some help please.

you don't have to use the encryption class but the session library requires a key. just put one in there and you'll be good to go.

this link generates random keys and even has a CI section: http://randomkeygen.com/

CI uses to make safer the use of the sessions

Thanks guys, I had put a key, but a question mark giving a error like this: domain.com/categories/article/?./1 in my url. I solved the problem by putting a key and config to enable query strings to false like this:

Code:

$config['enable_query_strings'] = FALSE;

Now everything works perfectly, thank again.
