TokenMismatchException in compiled.php line 2440:

Hi everyone

First, sorry for bad english, i sometimes speak english like a spanish cow.

I'm learning php and laravel and have a little problem. I added a scriptwall (for facebook-like functionalities) . I see it (the messages loading is working) but when i'm trying to save a new message (wich sould add a new entry in the database) i receive this message:

Whoops, looks like something went wrong.

The script is in ./wall (because it is an external resource) and the article.blade contains:

<?php include(app_path().'/../wall/index.php'); ?>

I think this problem is linked to laravel because the wall is working fine when not in laravel repository. Does anyone have a suggestion about how to fix that? Thanks by advance
