drupal break

Hello

I use FCK editor 2.6 Beta with drupal 5.7.
Initially this version comes with the plugins: teaser break and pagebreak.

I follow the instructions :

Open /drupal/sites/all/modules/fckeditor/fckeditor.config.js and uncomment these three lines:

FCKConfig.PluginsPath = '../../plugins/' ;
FCKConfig.Plugins.Add( 'drupalbreak' ) ;
FCKConfig.Plugins.Add( 'drupalpagebreak' )

and I add the buttons :

['Image','Flash','Table','Rule','SpecialChar', 'DrupalBreak', 'DrupalPageBreak']

but it doesn't work.

If someone has the solution with the modification of fckeditor.config.js or with the modification of the table fck_settings in mysql ?

thank's
