Here is the message we get (courtesy of a student who just got locked out!)

blank page with 'Disallowed Key Characters' in the top left corner"

Hi Rich,

You've encountered a protective layer in CodeIgniter (Scalar's underlying framework) that is a little too picky: there's a function that looks at the field names of incoming cookies and will display the error message and halt the application if there are special characters (e.g. ~ or @, etc). There's a few spam tracking cookies out there that can invoke this.

Are you using Scalar on our server (scalar.usc.edu)? If so, we already put in a patch that corrects this, so if the problem persists it means the patch needs enhancements and I can work to make it better.

Though, if you're using Scalar on your own server, the patch is to overwrite this file: "system/libraries/Input.php" in your Scalar root folder with: https://github.com/anvc/scalar/blob/master/system/libraries/Input.php

Thanks,
Craig

THanks Craig, We are running our own instance. I updated Input.php, and the site stayed up, so I assume we can close this issue.
