I adopted the instructions in this website there is however no such code within the comment.php. I am using Starkers theme there is however nothing inside which appears to manage the web site area.

Could it be inside a nw position now in Wordpress 3.?

Where's it?

The comment form is controlled through the comment_form() function. You've 2 options if you wish to change it's output:

  1. Alter the $fields argument whenever you refer to it as to get rid of the comment_author_url.
  2. Filter the creation of the function inside your theme's functions.php.

Fields argument

$your_fields =  array(

    'author' => '<p class="comment-form-author">' . '<label for="author">' . __( 'Name' ) . '</label> ' . ( $req ? '<span class="needed">*</span>' : '' ) .               '<input id="author" title="author" type="text" value="' . esc_attr( $commenter['comment_author'] ) . '" size="30"' . $aria_req . ' /></p>',

    'email'  => '<p class="comment-form-email"><label for="email">' . __( 'Email' ) . '</label> ' . ( $req ? '<span class="needed">*</span>' : '' ) . '<input id="email" title="email" type="text" value="' . esc_attr(  $commenter['comment_author_email'] ) . '" size="30"' . $aria_req . ' /></p>',

)

comment_form(array('fields' => $your_fields))

Filter

function your_comment_form_fields($the_form_fields)area from $the_form_fields

    return $the_form_fields



add_filter('comment_form_default_fields', 'your_comment_form_fields')

The publish below describes how you can take away the website area in the comment form. Becasue it is not specific to theme or core files, it will work in most recent and future versions of Wordpress.
