Hi Clayton,
If you download the plugin from here you will be able to fix the problem:
https://github.com/jeiseman/wp-show-posts
After using this version of the plugin, I put the following in my functions.php:
add_filter('wpsp_content_more_link', function() {
return null;
} );
add_filter( 'the_content_more_link', 'generate_custom_content_more', 16 );
function generate_custom_content_more( $more ) {
return ' <a class="read-more content-read-more" href="'. get_permalink( get_the_ID() ) . '">' . __('[continued...]', 'generate') . '</a>';
}Jon
