I added a few extra lines in the code to allow for page children to be visited by the user without being forbidden access.

First define the parent page by adding these 2 lines:

$parent_title = strtolower(get_the_title($post->post_parent));
$theparent = str_replace(‘ ‘, ”, $parent_title);

Next, in your if statement, add another or statement that allows a user access to the page if they are logged in and have the parent page username:

|| is_user_logged_in() && $username==$parent_title

In your clientpagetemplate.php page (whatever it’s name is!) The code is placed like this (These are not complete php statements, it’s just to help show location of new code.):

user_login );

$parent_title = strtolower(get_the_title($post->post_parent));
$theparent = str_replace(‘ ‘, ”, $parent_title);
?>

Best wishes!
