Showing posts and not excerpts

I've read the previous posts on how to do this & followed instructions

I changed <?php bfa_excerpt( 55, ' ...' ); ?> to <?php the_content(); ?> in the postformat.php file, but now all I get are posts (no header, no sidebars) when I try and hit my site.

I want to show post content, up to the "More" that I insert in my post. How can I do that?

Thanks!
