I have a pretty simple site whose page hierarchy looks a bit like this:

- A
  +-- A1
  +-- A2
  +-- A3
- B
  +-- B1
  +-- B2
  +-- B3
- C
  +-- C1
  +-- C2
  +-- C3

However, on the website itself, each top-level entry shows the second-level entries from all top-level entries, not just its own. So when I click on "B", I see all second-level entries from A1 to C3.

I really have no clue how this happened; I've never had this problem with Silverstripe. It doesn't seem to be theme-dependent; resetting to the original "simple" theme does not fix the problem. Flushing does not help. /dev/build does nothing. Is there something wrong with the database? I don't know, and I don't know what to do to test this idea, or fix the problem if it's true.

The Admin tools show the hierarchy just fine; it's only in the frontend where things are wrong.

I really have no idea where to even start to fix this problem. Any help?

Hi LKM,

I'm abit unsure about how much you know about SS.
But to me it sounds like a template issue.

Somwhere in your code there is an include statement (Page.ss) that inlcudes a navigation file. try to make a new navigation file, and put the following content into it - this should be an expanding menu - meaning only showing menu items under active menu.

<ul id="SubNavigation">
	<% control Menu(1) %>
	<li class="$LinkingMode lvl1 $FirstLast"><a href="$Link" title="$Title.XML" class="$LinkingMode levela">$MenuTitle.XML</a>
	
		<% if LinkOrSection = section %>
			<% if Children %>
				<ul class="SubLvl2">
					<% control Children %>
						<li class="lvl2"><a href="$Link" title="$Title.XML" class="$LinkingMode levelb">$MenuTitle.XML</a></li>
					<% end_control %>
				</ul>
			 <% end_if %>
		<% end_if %> 
	</li> 
	<% end_control %>
</ul>

Hope it helps, otherwise post more info and a version number please.

Is this a brand new 3.0 site? did you upgrade from 2.4 to 3.0? When did this problem occur? Does using a brand new database fix the problem?
