 * Hi Eric,
 * First of all, thanks for your plugin! I have some problem to use it, so I need
   your help.
    I understand I need to define `$wp_session = WP_Session::get_instance();`
   inside any session-dependent functions, like you said in other topic.
 * I do it inside a function that add some session variables. It’s ok. I print this
   variables on the same page to test it, and it’s fine.
 * On the second page, when I define again the `$wp_session = WP_Session::get_instance();`
   I get the error F
 * > atal error: Class ‘WP_Session’ not found…
 * . If I don’t define it, I can’t get the session variables.
 * What I’m doing wrong?
    Thank you very much!

 * I’d have to see your code, but my feeling would be that you’re trying to use `
   WP_Session` before the plugin’s been included and the class is available. Is 
   your code hooked to a specific action or just firing within a page?
