here's the problem:
FCKConfig.ToolbarSets["Default"] = [
]; /* Toolbar end */
this should be something more like:
FCKConfig.ToolbarSets["Custom"] = [
['FitWindow'],
['TextColor','BGColor'],
['Anchor'],
['Bold','Italic','-','OrderedList','UnorderedList','-','Link','Unlink','-','About']
]; /* Toolbar end */
try editing the HTMLEditor instance. Click the Customize button next to Editor Preset, go to the toolbar button and add the toolbars you wish to use.
