   I've got the latest version of wordpress installed.

   I'm writing text into the excerpt box in the 'add new post' box of the admin system and then calling this via the_excerpt() function.

   I've tried several ways of changing the default excerpt length from 55 to 10 words, including changing the excerpt_length in the formatting.php file, as well as adding the well known functions within my own theme's functions template that I found in the codex.

   Can anyone give me any pointers or codes where they have been successful in trimming the excerpt length?

   Much appreciated!

   Put this in your functions.php

   /* Create excerpt with 10 words and preserved HTML tags */
   function my_wp_trim_excerpt($text) {
   {
     if ( '' == $text ) {
     $text = get_the_content('');
     $text = apply_filters('the_content', $text);
     $text = str_replace(']]>', ']]&gt', $text);
     $excerpt_length = 10;
     $words = explode(' ', $text, $excerpt_length + 1);
     if (count($words) > $excerpt_length) {
       array_pop($words);
       array_push($words, '[...]');
       $text = implode(' ', $words);
       }
     }
   return $text;
   }
   
   // remove WordPress default excerpt filter
   remove_filter('get_the_excerpt', 'wp_trim_excerpt');
   // Add our custom filter with low priority
   add_filter('get_the_excerpt', my_wp_trim_excerpt, 20);
