problema con TinyMCE

ho eseguito le istruzioni previste per l'installazione di TinyMCE 5.x-1 con Drupal 5.1 - database PostgreSQL e cioè:

1. Place the entire tinymce directory into your Drupal modules/
directory.

2. Download TinyMCE 2.1 from

http://tinymce.moxiecode.com/

Remember to uncompress the file and make sure the folder is named
'tinymce'.

3. Place the entire 'tinymce' engine folder inside your modules/tinymce
directory. So the TinyMCE engine will live in modules/tinymce/tinymce

4. Enable this module by navigating to:

administer > modules

*note - all database tables will be automatically created during this step

5. Setup role based tinymce profiles via

administer > settings > tinymce

6. To boost the performance of TinyMCE, download the "TinyMCE compressor" from:

http://tinymce.moxiecode.com/download.php

Place the tiny_mce_gzip.php file in

modules/tinymce/tinymce/jscripts/tiny_mce

7. To use AJAX spell checking, download the spellchecker plugin:
(note: this requires TinyMCE 2.0.6+)

http://tinymce.moxiecode.com/download.php

Extract this file to

modules/tinymce/tinymce/jscripts/tiny_mce/plugins/

Then edit config.php in plugins/spellchecker/:

Uncomment this line and comment out all other require_once's:

require_once("classes/TinyGoogleSpell.class.php"); // Google web service

Set this to true:

$spellCheckerConfig['enabled'] = true;

Enable spellchecker in TinyMCE settings page, under "buttons and plugins"

Ma quando vado ad in serire un contenuto mi da un errore nel caricamento della pagine TinyMCE non è definito.

Qualcuno mi sa dare una mano.
