<?php

the link that you gave me I see the plugin page, but to write a post I still have to go in this section

I explained bad?

heeelp me please

what is the custom field?

I tried to create a page and insert the content @esmi have reported, but unfortunately I can see only the sidebar.

I also tried to create a page template by inserting the contents of the page category.php but WP just get me only the form for leaving comments.
