The issue is kind of strange because the codes that handles upload to s3 and the code that insert the ‘amazonS3_info’ post meta value are all located in the same function. In fact right after the main file is uploaded to s3 the next line of code is to insert the post meta value,then uploading the remaining thumbs to s3.
I need you to do one more check, for all the files that you uploaded while the malfunction occurred. Check your s3 bucket to see whether the main file and all its thumbs where actually uploaded to s3.
If the check above check is true, then we need to do a db upgrade so that these files are also served with their corresponding s3 url. Insert the below function in your functions.php file.

$s3_settings = get_option( 'tantan_wordpress_s3' );
        $bucket = $s3_settings['bucket'] ;
        $region = $s3_settings['region'];

	$args = array(
		'post_type' => 'attachment',
		'numberposts' => -1,
		'suppress_filters' => false
	);

	function filter_where( $where = '' ) {
		// change to the right start and end date
		$start_date = '2015-04-03'; $end_date = '2015-04-07';
		$where .= "AND post_date >= '{$start_date}' AND post_date <= '{$end_date}'";
		return $where;
	}
	add_filter( 'posts_where', 'filter_where' );
	$attachments = get_posts( $args );
	remove_filter( 'posts_where', 'filter_where' );

	$att_ids = array();
	foreach( $attachments as $attachment ) {
		$att_ids []= $attachment->ID;
	}

	$atts_info = array();
	foreach( $att_ids as $id ) {
		$prefix = $s3_settings['object-prefix'];
		$att_file = get_post_meta( $id , '_wp_attached_file', true );
		$att_basename = basename($att_file);
		if ( !empty( $prefix) ){
			$key = $prefix.$att_basename;
		} else {
			$key = $att_basename;
		}
		$args = array(
			'id' => $id,
			'key' => $key
		);
		$atts_info []= $args;
	}

	foreach( $atts_info as $att_info ) {
		$args = array (
			'bucket' => $bucket,
			'key' => $att_info['key'],
			'region' => $region,
		);
		update_post_meta( $att_info['id'], 'amazonS3_info', $args );
	}

Make sure the plugin settings is actually the same when you had the issue please, because the code will be using the bucket, prefix and region settings of the plugin.

$start_date and $end_date should be the dates in between the malfunction, so we should be working only with the needed attachments and should be in the format `$tart_date = ‘yyyy-mm-dd’ for example.
After running the above db upgrade you should be good. Please don’t forget to remove the codes after you are done.

On second thought, this is what you will do. While saving your manual excerpt in the post edit screen, type for example ‘[..]’ at the end of the excerpts, Do not use the string ‘[…]` as it will be interpreted as a symbol or any other string that will also be interpreted as a symbol. Then update the last codes I posted replacing the two occurrence of string'[…]’ with ‘[..]’. It ‘s working on my end.

I hope you did not replace the entire code in the function with the line of code I suggested above. Your finally code should like this:

function custom_excerpt($text) {  // custom 'read more' link
   if (strpos($text, '[...]')) {
      $excerpt = strip_tags(str_replace('[...]', '<div class="readmore"><a class="readmore" href="'. get_permalink( get_the_ID() ) . '"><small>CONTINUE READING</small></a></div>', $text), "<a>");
   } else {
      $excerpt = '<div class="readmore"><a class="readmore" href="'. get_permalink( get_the_ID() ) . '"><small>CONTINUE READING</small></a></div>';
   }
   return $excerpt;
}
add_filter('the_excerpt', 'custom_excerpt');

Change this line:

$excerpt = '' . strip_tags($text) . '<div class="readmore"><a class="readmore" href="'. get_permalink( get_the_ID() ) . '"><small>CONTINUE READING</small></a></div>';

to this:

$excerpt = '<div class="readmore"><a class="readmore" href="'. get_permalink( get_the_ID() ) . '"><small>CONTINUE READING</small></a></div>';

One more suggestion, just try to make your codes as DRY as possible. I see repetitions in your codes.

Thanks..

Something like this would work:

add_filter( 'media_send_to_editor', 'mp3_media_insert', 20, 3 );
function mp3_media_insert( $html, $id, $attachment ){
	$output = '';
	$post = get_post( $id );
	if ( 'audio/mpeg' == $post->post_mime_type ) {
		$output .= '<strong>MP3:</strong>';
		$output .= '<a href="'.$attachment[url].'">'.$post->post_title.'</a>';
		$output .= $html;
		return $output;
	} else {
		return $html;
	}
}

So so sorry..I double checked the EWWW file and the code I reference above was actually hooked to wp_generate_attachment_metadata instead of wp_update_attachment_metadata. My mistake,sorry for the headache, and yes your code should work by switching to wp_generate_attachment_metadata because it is called before wp_update_attachment_metadata. Sorry…
