Make the following changes:
In template/customer/account/dashboard/info.phtml
<div class="inner-head">
<h5><?php echo $this->__('Contact Information') ?></h5>
Edit
</div>
<p>
<?php echo $this->htmlEscape($this->getCustomer()->getFirstname()) ?>
<?php echo $this->htmlEscape($this->getCustomer()->getLastname()) ?><br />
<?php echo $this->htmlEscape($this->getCustomer()->getEmail()) ?><br />
<?php echo $this->__('Change Password') ?>
</p>
and Replace with:
<div class="inner-head">
<h5><?php echo $this->__('Contact Information') ?></h5><br />
</div>
<p>
<?php echo $this->htmlEscape($this->getCustomer()->getFirstname()) ?>
<?php echo $this->htmlEscape($this->getCustomer()->getLastname()) ?><br />
<?php echo $this->__('Change Password') ?>
</p>

The problem was that we had an extension that override the user model/controller/view, example: social login, and because we decided not to use it we Disable it in the advanced settings.
Because it was disable, the list of users was not showing in the back-end, but I could create a new customer, yet in the New customer view the Addresses were not showing either.
So, we activated all the extensions again and suddenly the customers list appears. So like this we found out which extension was breaking and fixed it.

In file :
app\code\core\Mage\Customer\controllers\AccountController.php
/**
* Change customer password action
*/
public function editPostAction()
{
if (!$this->_validateFormKey()) {
return $this->_redirect('*/*/edit');
}
if ($this->getRequest()->isPost()) {
$customer = Mage::getModel('customer/customer')
->setId($this->_getSession()->getCustomerId())
->setWebsiteId($this->_getSession()->getCustomer()->getWebsiteId());
$fields = Mage::getConfig()->getFieldset('customer_account');
$data = $this->_filterPostData($this->getRequest()->getPost());
//=========
// ADD THAT // customer cannot change his email // Le customer ne peut pas modifier son email
if(isset($data['email'])){
$data['email'] = $this->_getSession()->getCustomer()->getData('email');
}
//========END
foreach ($fields as $code=>$node) {
if ($node->is('update') && isset($data[$code])) {
$customer->setData($code, $data[$code]);
}
}
$errors = $customer->validate();
if (!is_array($errors)) {
$errors = array();
}
