My b2evolution Version: 4.1.x

Hello all.

I am inserting a widget to show current posts and inserted a new container as shown below yet it is not working. Inserted into index.main.php and post.main.php although I only want it on front page and therefore hope to remove it from post.main.php.

index.main.php

<?php
		// -------------- MAIN CONTENT TEMPLATE INCLUDED HERE (Based on $disp) --------------
		skin_include( '$disp$', array(
			) );
		// Note: you can customize any of the sub templates included here by
		// copying the matching php file into your skin directory.
		// ------------------------- END OF MAIN CONTENT TEMPLATE ---------------------------
	?>


	<?php
	{	// ----------------------- MAIN LOWER CONTENT START ------------------------------------
		skin_container( NT_('Main_Lower'), array( 
        'block_start'  => '<div class="$wi_class$">', 
        'block_end'   => '</div>', 
    ) );  
		// ----------------------- MAIN LOWER CONTENT END ------------------------------------
	}
	?>

post.main.php

<?php
	// Go Grab the featured post:
	if( $Item = & get_featured_Item() )
	{	// We have a featured/intro post to display:
		// ---------------------- ITEM BLOCK INCLUDED HERE ------------------------
		skin_include( '_item_block.inc.php', array(
				'feature_block' => true,
				'content_mode' => 'auto',		// 'auto' will auto select depending on $disp-detail
				'intro_mode'   => 'normal',	// Intro posts will be displayed in normal mode
				'item_class'   => 'featurepost',
				'image_size'	 =>	'fit-400x320',
			) );
		// ----------------------------END ITEM BLOCK  ----------------------------
	}
	?>


	<?php
	{	// ----------------------- MAIN LOWER CONTENT START ------------------------------------
		skin_container( NT_('Main_Lower'), array( 
        'block_start'  => '<div class="$wi_class$">', 
        'block_end'   => '</div>', 
    ) );  
		// ----------------------- MAIN LOWER CONTENT END ------------------------------------
	}
	?>
