Html for posts in blank

Sorry for my english.
I’m a newbie.
Aparently I made all right:
install hugo;
upload the themes;
make new site;
run hugo for create the html.
The site is created with the principal page and posts listed.
But the html for posts is in blank!
Is there anything I may have done wrong?

Hello @Henry_Mazer,

could you post the directory structure of your Hugo site and the theme that you are currently using?
