my folder structure :

root
setup.php
   >user
      >themes
         >MainTheme
            >template
            >css
            >blueprints
            > etc...
      >sites
         >themes
            >subsite A
               >config
               >pages
               >themes
                  >MainTheme 
                     >css
                        - custom.css
            >subsite B

My issue is only with modular page. the page is not rendering.
when i {{dump(page.collection())}} in modular.html.twig i can see modular pages in debug bar

my modular.md

title: Home
publish_date: '03-08-2016 18:25'
content:
    items: '@self.modular'
    order:
        by: default
        dir: asc
        custom:
            - _slideshow
