I know how you activate the ‘load more button’ via ‘Costumizer’, General - homepage - * Enable Load More Button on Homepage.

My ‘home page - home’ is a single page, i use this code to get the latest posts:

[penci_index title=“” cat=“” numbers_posts=“12” columns=“3” display_title=“yes” " display_cat=“no” display_date=“yes” display_image=“yes” image_size=“horizontal” cat_link=“no” cat_link_text=“meer” /]

is there otherwise an option to get the load more posts button?
