title: Displaying menu names from CMS
body: <p>I have been trying to display a menu name from my CMS database that I created myself, I got it displayed perfectly but there is a really weird error, I spent many hours to discover the solution but I couldn't.</p>
  
  <p>The problem is that I want to display the menu name as page H1 in line 50 exactly so whenever you click on the menu name its also displaying as H1 title.</p>
  
  <p>The menu name is displaying correctly, but the sub menu(pages) displaying N instead of the page name, I don't know where is that N is coming from.</p>
  
  <p>NOTE: There is no problem with the database connection or retrieving data.</p>
  
  <p>This is my content page code:</p>

  } elseif (isset ( $_GET ['pages'] )) {
      $sel_subject = false;
      $sel_page = get_page_by_id ( $_GET ['pages'] );
