Share wishlist email not being sent

Question

Emails are being sent correctly (subsription, registration, etc...), but the share wishlist email is not being sent.

Email is not present in admin panel system/tools/SMTPPro - Email Log.

Where I should begin to look to find what's not working? Which are the best steps to find the origin of the problem?

If I go to magento_path/app/design/frontend/theme/template/wishlist/sharing.phtml

I see that the share wishlist button is in a form, and the action form is <form action="<?php echo $this->getSendUrl() ?>" id="form-validate" method="post">.

So I look into magento_path/app/code/core/Mage/wishlist/Block/Customer/Sharing.php where getSendUrl() method is. And I place a log in this method:

Mage::log($this->getUrl('*/*/send'), Zend_Log::INFO, 'email_send.log', true);

The log in the file after trying to send the share email is:

2018-01-29T09:16:02+00:00 INFO (6): https://myweb.com/en/wishlist/index/send/

Once I see this I look into the wishlist index controller, the sendAction. And I place some logs there:

$emails  = explode(',', $this->getRequest()->getPost('emails'));
Mage::log($emails, Zend_Log::INFO, 'email_send.log', true);
$message = nl2br(htmlspecialchars((string) $this->getRequest()->getPost('message')));
Mage::log($message, Zend_Log::INFO, 'email_send.log', true);

the $emails var is:

2018-01-29T09:28:47+00:00 INFO (6): Array
(
    [0] => pim@youremail.cf
)

That is the email in entered

and the $message var is:

2018-01-29T09:28:47+00:00 INFO (6): 
<div style="border:1px solid #E0E0E0; padding:15px; background:#F9F9F9;">
    <table cellspacing="0" cellpadding="0" border="0" width="650">
        <tr>
            <td width="32%">
                <p align="center" style="font-size:12px;"><a href="https://myweb.com/en/foo-sunset-eclipse.html"><img src="https://myweb.com/media/catalog/product/cache/1/small_image/135x/9df78eab3352/F/o/foo-sunset-eclipse.jpg" style="border:1px solid #ccc;" width="135" height="135" alt="" /></a></p>
                <p align="center" style="font-size:12px;"><a href="https://myweb.com/en/foo-sunset-eclipse.html" style="color:#203548;"><strong>foo sunset eclipse/ natural</strong></a></p>
                <p align="center" style="font-size:12px;"><a href="https://myweb.com/en/foo-sunset-eclipse.html" style="color:#1E7EC8;">Product view</a> <small>
            |</small> <a href="https://myweb.com/en/checkout/cart/add/uenc/aHR0cHb3oyLmJlbm29tLdpc2hsaXNQv/product/1210/form_key/vtdo2iaN/nocookie/1/" style="color:#1E7EC8;"><strong>Add to Cart</strong></a>            </p></td>
            <td width="2%"></td>
    </table>
</div>

that is the email template I'm trying to send.

Edit: Solution

I find the wishlist email sending code from the wishlist indexcontroller commented. I uncomment it and now emails are sent:

//this code was commented. So it prevented wishlist emails from being sent
foreach ($emails as $email) {
            $emailModel->sendTransactional(
                Mage::getStoreConfig('wishlist/email/email_template'),
                Mage::getStoreConfig('wishlist/email/email_identity'),
                $email,
                null,
                array(
                    'customer'       => $customer,
                    'salable'        => $wishlist->isSalable() ? 'yes' : '',
                    'items'          => $wishlistBlock,
                    'addAllLink'     => Mage::getUrl('*/shared/allcart', array('code' => $sharingCode)),
                    'viewOnSiteLink' => Mage::getUrl('*/shared/index', array('code' => $sharingCode)),
                    'message'        => $message
                )
            );
        }

I find the wishlist email sending code from the wishlist indexcontroller commented. I uncomment it and now emails are sent:

magento_path/app/code/core/Mage/Wishlist/controllers/indexController.php look for sendAction() method.

//this code was commented. So it prevented wishlist emails from being sent
foreach ($emails as $email) {
            $emailModel->sendTransactional(
                Mage::getStoreConfig('wishlist/email/email_template'),
                Mage::getStoreConfig('wishlist/email/email_identity'),
                $email,
                null,
                array(
                    'customer'       => $customer,
                    'salable'        => $wishlist->isSalable() ? 'yes' : '',
                    'items'          => $wishlistBlock,
                    'addAllLink'     => Mage::getUrl('*/shared/allcart', array('code' => $sharingCode)),
                    'viewOnSiteLink' => Mage::getUrl('*/shared/index', array('code' => $sharingCode)),
                    'message'        => $message
                )
            );
        }

I know that code/core code should never be edited, it must be overwritten instead.
