Top Level pages in wordpress giving 404, but child pages working fine

Basically everything works fine except for the top level pages ( e.g. category, archives, single post, custom post type, etc…).

I have 3 custom post types and 4 custom taxonomies (each custom taxonomy is attached to a post type respectively and there is one more taxonomy that is attached to all of the post types). Here is the set up for both of them:

register_taxonomy(
    'newsroom-topics',
    array ( 0 => 'news-post',),
    array (
        'hierarchical' => true, 
        'label' => 'Newsroom Topics',
        'show_ui' => true,
        'query_var' => true,
        'rewrite' => array('slug' => '/'),
        'singular_label' => 'Newsroom Topic'
    ) 
 );

register_post_type(
    'news-post',
    array(  
        'label' => 'Newsroom Posts',
        'description' => '',
        'public' => true,
        'show_ui' => true,
        'show_in_menu' => true,
        'capability_type' => 'post',
        'hierarchical' => false,
        'rewrite' => array('slug' => 'newsroom'),
        'query_var' => true,
        'has_archive' => true,
        'exclude_from_search' => false,
        'menu_position' => 5,
        'supports' => array('title','editor','excerpt','trackbacks','custom-fields','comments','revisions','thumbnail','author','page-attributes','post-formats',),
        'taxonomies' => array('content-type','newsroom-topics',),
              'labels' => array (
              'name' => 'Newsroom Posts',
              'singular_name' => 'Newsroom Post',
              'menu_name' => 'Newsroom Posts',
              'add_new' => 'Add Newsroom Post',
              'add_new_item' => 'Add New Newsroom Post',
              'edit' => 'Edit',
              'edit_item' => 'Edit Newsroom Post',
              'new_item' => 'New Newsroom Post',
              'view' => 'View Newsroom Post',
              'view_item' => 'View Newsroom Post',
              'search_items' => 'Search Newsroom Posts',
              'not_found' => 'No Newsroom Posts Found',
              'not_found_in_trash' => 'No Newsroom Posts Found in Trash',
              'parent' => 'Parent Newsroom Post',
),) );

Any thoughts as to why this is happening?

UPDATE:

So after having just post this after a while of looking for why this was happening, i found out the problem. In the reading settings, my front page was set to be displayed as a static page, and when i changed it back to the default, everything worked fine.
