this theme has a missing tag, just thought that you might want to know:
one closing </div> missing in the comments.php:
<p><?php _e('You must be','slt');?> /wp-login.php?redirect_to=<?php the_permalink(); ?>"><?php _e('logged in','slt');?> <?php _e('to post a comment.','slt');?></p><!-- xCSx --></div><!-- xCSx -->
the one enclosed in <!-- xCSx --> is the one missing
without the closing div tag, logged out user will see a misaligned layout on single page post.
