Hi,

I am very new to Silverstripe and is doing the tutorial 2 on 'Extending a basic site' from this linki
http://doc.silverstripe.org/sapphire/en/tutorials/2-extending-a-basic-site

After I added the code below to the ArticlePage.php in mysite\code, then I flush the cache. I view the CMS and now besides the 'Home', 'About Us', 'Contact Us', 'Page Not Found', and 'Server Error' pages, I now also have 11 blank or empty pages under the page trees.

<?php
class ArticlePage extends Page {
// ...

function getCMSFields() {
$fields = parent::getCMSFields();

$fields->addFieldToTab('Root.Content.Main', new DateField('Date'), 'Content');
$fields->addFieldToTab('Root.Content.Main', new TextField('Author'), 'Content');

return $fields;
}
}

// ...

Why are these blank pages added? I have attached the print screen... appreciates greatly if anyone can help. Thanks.
