Hi,
I have a question.
If I should change the bfa_loop( ) function to show the post at the start page, with this structure:

Last Post for category one
______________________
Last Post for category two
______________________
Last Post for category three
______________________
Last Post for category four

Basically , I want to show the last article for all single category in my blog.
I saw that the bfa_loop function( ), show all article regardless of category.
Can I change the bfa_loop( ) fuction without the change is lost in case update theme?

Any change to the themes code will be lost over an update of the theme.

Yes, I imagined it was so.
But if if you employ the child theme WP functionality, changing montezuma code, you could have user to able a child theme to redefine a function in parent.
For example for bfa_loop() you should change montezumas'code with this:

if (!function_exists( 'bfa_loop' ) ){
   function bfa_loop() {
     ....
   }
}

Exploiting the mechanism of child theme, I can create a file in directory includes/ of my child theme to redefine bfa_loop function and include it whitout an redeclaration error.
To do this, however, we should change the montezuma's core.
I hope you have understood me.

I solve it whitout child theme

Care to explain your solution for others?

I have create a virtual main template named home.php in Montezuma Options -> Main Templates, with this code:

<!--<div id="container">-->

<?php get_header(); ?>

<div id="main" class="row">
        
        <div id="widgetarea-one" class="col4">
		<?php dynamic_sidebar( 'Widget Area ONE' ); ?>
	</div>

	<div id="content" class="cf col8">
		
		<div class="my-category">
              		<?php bfa_custom_query( 'category_name=category_oneshowposts=1' ); ?>
                  
                	<?php bfa_loop( 'postformat' ); ?>
              </div>
              <div class="my-category">
              		<?php bfa_custom_query( 'category_name=category_two&showposts=1' ); ?>
                  
                	<?php bfa_loop( 'postformat' ); ?>
              </div>
              <div class="my-category">
              		<?php bfa_custom_query( 'category_name=category_three&showposts=1' ); ?>
                  
                	<?php bfa_loop( 'postformat' ); ?>
              </div>
              <div class="my-category">
              		<?php bfa_custom_query( 'category_name=category_four&showposts=1' ); ?>
                  
                	<?php bfa_loop( 'postformat' ); ?>
              </div
	</div>
	
	<div id="widgetarea-two" class="col4">
		<?php dynamic_sidebar( 'Widget Area TWO' ); ?>
	</div>

</div>
	
<?php get_footer(); ?>

<!--</div>-->

This code, create four section, one for each Post's category and show only last Post of each category, by executing query_post() function before loop.
After, I have create a Page named Home and I assigned the Virtual Main Template home.php created, by dropdown "Virtual Template" on the right bottom.
Finally, I assigned in WP -> Read -> Front page displayes, A static page (select below) -> Front page: Home.

Nicely done! And thanks for sharing.
