in the loop-entry.php there is
<h2><a href="https://wordpress.stackexchange.com/questions/295028/<?php the_permalink(" ') ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></h2>
change above code to
<h2><a href="https://wordpress.stackexchange.com/questions/295028/<?php echo get_permalink( $post->ID ); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></h2>
Done!
