No sent mail oc2.2.0.0

Good I have a problem that brings me head, oc not send me any mail or registration or order forms, and have tried everything not know what else I can do, mail and SMTP, SMTP in the contact form strip me mistake, but in no case sends you mail .... that happens has happened to someone else in this version?

File: opencart\admin\view\template\marketing\contact.tpl line 194:

// Summer not fix
$('textarea[name=\'message\']').val($('#input-message').code());
cause JS error:

Uncaught TypeError: $(...).code is not a function
Cause summernote API has changed.

Proposed solution: comment out or delete offending code

// Summer not fix
// $('textarea[name=\'message\']').val($('#input-message').code());
