how edit Read More text

Greetings, I am using the template called minamaze in the latest version of wordpress, which is 4.2. Now this template did a child theme to keep my changes are lost when you update the parent template.

From what I have researched to make the change to the red button that says “Read More” have to copy and modify my theme child next file, while respecting the directory tree: admin\main\options2.homepage.php

the code of which I speak is this:

if ( ! empty( $slide['slide_url'] ) ) {
   echo '<div class="featured-link">',
                                         '<a href="' . $slide['slide_url'] . '"><span>' . __( 'Read More', 'lan-thinkupthemes' ) . '</a></span>',
                                         '</div>';
}

where “Read More” he says Read More want to say, but when you save and reload the page, these are not shown.

If I was not missing any step when you think my child theme I do not think that, before this modify the footer, and whether changes are reflected.

Still I show you the code file named according funtions.php that is so you can run the implementation of child theme:

<?php

function mh_child_style() {
        wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );
}

add_action( 'wp_enqueue_scripts', 'mh_child_style' , 5 );

?>
