Try this basic template layout
<?php
get_header(); # gets header.php contents
if (have_posts()): # checks if there are any post available for this url
while(have_posts()): # starts loop
the_post(); # assigns $posts global
the_title(); # outputs post title
the_content(); # outputs post content
endwhile; # ends loop
endif; # ends conditional check
get_footer(); # gets footer.php contents
