Finally, it did start working but it was kinda bizarre as it wouldn't show posts properly at first, but started working correctly the next day, even with fresh posts.
There's one more thing I am working on with this. I would like to be able to display the blog name associated with each post. I assumed that the plugin would do that, but all I am getting is the post title. Here's the code I am using for home.php:
<?php
if (have_posts()) : ?><?php while (have_posts()) : the_post(); ?>
<a href="http://<?php echo $details[ 'domain' ] . $details[ 'path' ] ?>"><?php echo get_blog_option( $details[ 'blog_id' ], 'blogname' ) ?></a><br />
<a href="<?php the_permalink() ?>" title="Permanent Link to <?php the_title(); ?>" target="_blank" rel="bookmark"><?php the_title();?> </a>
<?php the_content(''); ?>
<?php endwhile; ?><?php endif; ?>
I was originally thinking that
<a href="http://<?php echo $details[ 'domain' ] . $details[ 'path' ] ?>"><?php echo get_blog_option( $details[ 'blog_id' ], 'blogname' ) ?></a>
would automatically display the blog associated with a particular post, but it only displays the main blogname.
Am I going to have to try to edit the plugin to show the blog name as well?
