 * I’ve just installed the plugin but I still got this 500 error.
 * _Si è verificato un errore nel sito web durante il recupero di [http://cioccolatoextravergine.it/wp-admin/admin-post.php?action=activate\_plugin](http://cioccolatoextravergine.it/wp-admin/admin-post.php?action=activate_plugin).
   Potrebbe non essere disponibile per manutenzione o essere configurato in modo
   errato._
 * Plus, if I try to signup on your site the captcha is always wrong.
 * How possible I am always typing the wrong captcha, with a 3 digit, only numbers
   code?
 * Thank you,
 * D.R.
