Blog posts won't show "Except" with more button

Hey cfleury!

You can use the read more quicktag: http://en.support.wordpress.com/splitting-content/more-tag/ to create the excerpt or insert following code at the bottom of functions.php:

add_filter( 'post-format-standard', 'avia_category_content_filter', 15, 1);
function avia_category_content_filter($current_post)
{
if(!is_single())
{
	$current_post['content'] =  get_the_excerpt();
	$current_post['content'] .= $current_post['content'].'<div class="read-more-link"><a href="'.get_permalink().'" class="more-link">'.__('Read more','avia_framework').'<span class="more-link-arrow">  &rarr;</span></a></div>';
}
return $current_post;
}

to use the “excerpt” field content for the excerpt text.

Best regards,
Peter
