Read more Button

Hi,
about a year ago I removed the "Read more" Button.
Now I would like to add it again, but I have no Idea how to.
Could you help me?

Hi, Download your theme here and upload to your site.

Hi,
well that's the thing I don't want to do. It took me quite a long time to modify the theme to my needs. I'm not an expert, so it's not easy for me.
I don't want to redo the site all over again.
I want to know what to write and where.

Hi!
It depends on how you removed the "Read more" Button.
Usually there is the code:

<?php
				//Post content
				if (!is_single()&&!is_page()) { 
					smtheme_excerpt('echo=1');
					?><a href='<?php the_permalink(); ?>' class='readmore'><?php echo $SMTheme->_( 'readmore' ); ?></a><?php
				} else {
					the_content('');
				}
				wp_link_pages(); ?>

in the file theloop.php. Try to find it. Probably, you have removed the line:

<a href='<?php the_permalink(); ?>' class='readmore'><?php echo $SMTheme->_( 'readmore' ); ?></a>

Thanks a lot, that was exactly the line I removed.
