Open the functions.php file located in your current theme folder and add (copy and paste) the following code, you won't need to use nor plugin, nor manual excerpts:


function custom_wp_trim_excerpt($text) {
$raw_excerpt = $text;
if ( '' == $text ) {
//Retrieve the post content.
$text = get_the_content('');

//Delete all shortcode tags from the content.
$text = strip_shortcodes( $text );

$text = apply_filters('the_content', $text);
$text = str_replace(']]>', ']]>', $text);

$allowed_tags = '<a>';
$text = strip_tags($text, $allowed_tags);

$excerpt_word_count = 55; /*** MODIFY THIS. change the excerpt word count to any integer you like.***/
$excerpt_length = apply_filters('excerpt_length', $excerpt_word_count);

$excerpt_end = '[...]'; /*** MODIFY THIS. change the excerpt endind to something else.***/
$excerpt_more = apply_filters('excerpt_more', ' ' . $excerpt_end);

$words = preg_split("/[\n\r\t ]+/", $text, $excerpt_length + 1, PREG_SPLIT_NO_EMPTY);
if ( count($words) > $excerpt_length ) {
array_pop($words);
$text = implode(' ', $words);
$text = $text . $excerpt_more;
} else {
$text = implode(' ', $words);
}
}
return apply_filters('wp_trim_excerpt', $text, $raw_excerpt);
}

remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'custom_wp_trim_excerpt');


You can include more tags in $allowed_tags var.
