Theme[thebox] still showing excerpts

Hey guys, I’ve been struggling with this for several hours, reading up on possible fixes, and etc, trying to figure out how to change The Box theme’s tiny default excerpts into fully displayed posts.

I have tried replacing the_excerpt() with the_content() and this has not worked.

I have tried changing the $excerpt = implode(" ",$excerpt)."... <br><a class=\"more-link\" href='" .get_permalink($post->ID) ." '>".__('Read more', 'thebox')." &raquo;</a>"; (in the functions.php) to various other forms of the_content() and it only breaks the site.

The loop in my single.php file reads `<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>
<?php the_content(); ?>
<?php endwhile; ?>
<?php endif; ?>`

I can’t imagine what else needs to be done. It’s very irritating because the ‘read more’ is only 3 words long. Any help would be appreciated!
Thanks.
