 * is_admin is a default WordPress function – so it’s possible you may need to download
   WordPress again and overwrite the files.

 * If this is a new install, simply re-upload a **fresh** copy of WordPress 3.0.4.

 * i check it, and i found the source code of the function:
    in /wp-admin/load-scripts.
   php -> line 68:
 *     ```
       function is_admin() {return true;}'
       in  /wp-admin/load-styles.php -> line 68:
       <code>function is_admin() {return true;}</code>
       and in  /wp-includes/load.php -> line 572:
       ```
   
 * function is_admin() {
    if ( defined( ‘WP_ADMIN’ ) ) return WP_ADMIN; return false;}`
   so!! it look strange to me that the function is UNDEFINED 🙁

 * If it’s not defined on your install, then something’s wrong. Seriously. Redownload
   the whole wordpress install and copy it to your server. Something did not get
   uploaded correctly the first time.
