Help with Morning After theme

I’ve got a few issues I can’t seem to solve with this theme.

I’m customizing it at https://www.fernandosouza.org, and I can’t seem to show the full post instead of only an excerpt. I tried editing index.php and replacing <?php the_excerpt(); ?><?php the_meta(); ?> for <?php the_content(); ?><?php the_meta(); ?> but it didn’t work, it still showed the excerpt. Well, help me with this issue first and then I’ll ask another one.

Thanks a lot!
