 * Hi Everybody!
 * I have a problem when I want to insert some new categories : ‘Call to undefined
   function term_exists() in wp-admin/includes/taxonomy.php’
 * Here it is the addcategory.php file.

 * With an out of the box WordPress installation this should work. What I recommend
   it:
 * 1. Download the latest version of WordPress from [here](http://wordpress.org/download/)
   or the version you are using from [here](http://wordpress.org/download/release-archive/)(
   if you are running an older version). (note that ideally you should always run
   the latest version)
 * 2. Re-copy all the files.
 * 3. If it is still not working, then start by disabling the plugins 1 by 1 and
   try each time you disable a plugin.
 * 4. If after all plugins has been disabled, then try reverting to the default 
   theme.
 * This should work and should help you find out what is causing such an issue.

 * Alright,
 * I’ve change my method, I use
 *     ```
       if(!is_term($term, $taxonomy)){
         wp_insert_term($term, $taxonomy, $args);
       }
       ```
   
 * Thanks for your help
