The same will go for the following file:

/includes/templates/YOUR_TEMPLATE/templates/tpl_timeout_default.php

It will be missing this line:

<?php echo zen_draw_hidden_field('securityToken', $_SESSION['securityToken']); ?>

This is what it should look like:

<label class="inputLabel" for="login-password"><?php echo ENTRY_PASSWORD; ?></label>
<?php echo zen_draw_password_field('password', '', zen_set_field_length(TABLE_CUSTOMERS, 'customers_password') . ' id="login-password"'); ?>
<br class="clearBoth" />
<?php echo zen_draw_hidden_field('securityToken', $_SESSION['securityToken']); ?>
</fieldset>
