Hi,
I upgraded Wordpress to 3.5.1 last days, and now my Contact Form is not working. From user perspective there is an info like failed to send your message, but in Admin Area, in CF7 settings page, there are php errors like:
--- body --
<b>Notice</b>: Undefined index: body in <b>/wp-content/plugins/contact-form-7/admin/includes/meta-boxes.php</b> on line <b>81</b>
