How to delet "read more" on main

To actually remove them you would have to copy the widget code into a functions.php file in a child theme. Alternately, you can just suppress them from displaying with CSS:
a.more-link { display:none; }

In file “interface_widgets.php” i delete this code:

” href=”<?php the_permalink(); ?>”>
<?php _e( ‘Read more’,’interface’ ); ?>

Resolved.
