Using stripe to process Bitcoin - TokenMismatchException in VerifyCsrfToken.php line 67:

I have just installed the Stripe package for my e-commerce app, and I get this error every time I try to checkout of the site, including test mode. I have the following routes file

/*
|--------------------------------------------------------------------------
| Application Routes
|--------------------------------------------------------------------------
|
| Here is where you can register all of the routes for an application.
| It's a breeze. Simply tell Laravel the URIs it should respond to
| and give it the controller to call when that URI is requested.
