Thanks Michael it works ! but with this mod:
syndication permalink = syndication_permalink
i think you have mistyped the field name.
So the full code to show the link to original article from the rss source will be:
<?php
$link = get_post_meta($post->ID, 'syndication_permalink', true);
if ($link){
echo '<a href="'.$link.'">Read original story</a>';
}
?>
I placed it in single.php after <?php the_content(); ?> .
Hope this help anyone in the same trouble.
Thank you mercime for reply,
yes is true that WPMU needs heavy work to check each subdomains (in my case 300…).
Il try some tests with WP “classic”.
Thanks again.
