Yes you’re right acosmin I createad a new .php file (post-full.php), and then copy-paste the file Full Width Page.php and changed at the beggining: “Template name: Full Width Page” for “Template name Posts: Full Width Page”. So I can have full width posts. Now I’ve checked on this new file and I’ve introduced “<?php comments_template()” where you told me and comments are working.
Thank you for your help. I really like your Theme but I hope in some update you give us the option to have full width posts (without the sidebar). Thanks again!
