Page not appearing when using ->children

[gnome]

Hi all

I've been using ProcessWire for a while and am completely comfortable using it. BUT, for some reason, today I am unable to echo out a page link!

I have a section (About Us), which did have 4 children. Today I have added a 5th child page, but it refuses to be added to the navigation. I've echoed out the count of children and it is coming back as 4, even though there are now 5. The page is published and saves fine. I've deleted it and re-added it, to no avail.

Has anyone else ever had this issue? Any suggestions more than welcome!

Code for generating menu is below.

$navigation = $page->rootParent->navigation;

if(count($navigation) > 0)
{
	//echo count($navigation);
	foreach($navigation as $p)
	{						
		$children = $p->children;
		//echo $p->url;
		//echo count($children);
		
		// count children (exclude certain templates)
		if(count($children) && $p->is("template!=news-page|team-page|development-land-page|sheep-sales-page|produce-sales-page|grass-keep-page|property-list-page|property-auctions-page"))
		{
			// accordion header
			?>
			<a href="#" class="submenu<?php if($page->parents->has($p) || $p === $page) echo '-current'; ?>"><?= $p->title; ?></a>
			<?php
			// expandable sub-menu
			?>
			<div class="sub-sub-links <?php if($page->parents->has($p) || $p === $page) echo 'active'; ?>">
				<?php
				foreach($children as $child)
				{
					?>
					<a href="<?= $child->url; ?>" <?php if($child === $page) echo 'class="sub-sub-links-current"'; ?>><?= $child->title; ?></a>
					<?php
				}
				?>
			</div>
			<?php
		}
		else
		{
			// single page
			if ($page->parents->has($p) || $p === $page)
			{
				$class = 'sub-links-current';
			}
			else
			{
				$class = '';
			}
			?>
			<a href="<?= $p->url; ?>" class="<?= $class; ?>"><?= $p->title; ?></a>
			<?php
		}
	}

Isn't that page set to "hidden"?

[gnome]

No, definitely not hidden.

It just can't be. Make sure you're on the right install/page etc or something.

[gnome]

Definitely on the right domain. I've taken a screen grab. This is what ProcessWire says:

And this is what the code above outputs:

[Soma]

What does that output for you when directly grabed?

echo $pages->get("/about/")->children;

echo $pages->get("/about/")->children->count;

what is this rooparent "navigation" you get the 

[diogo]

You can also try $pages->find("parent=/about-us/") and $pages->find("parent=/about-us/, include=all") just to see what you get

Thank-you Soma! For mentioning the "navigation" field. It turns out that this is used to generate the menu, rather than just getting the page children. So you have to manually add the new page(s) to the navigation field for it to appear in the menu. Thank-you to all for your help  and suggestions.
