Ok, maybe between the two of us we can get this working. I looked at your site and you have the same problem I ran into today trying to get this working. The SpellerPages requires 2 file downloads from this location http://aspell.net/win32/ , you need the full installer and a dictionary. I ran the installer and loaded the English dictionary on my dotnetnuke server.
The main problem I had was with the web.config file, there are two FCKconfig.js files in the Fck folder.
- Providers\HtmlEditorProviders\Fck\Custom\fckconfig.js
- Providers\HtmlEditorProviders\Fck\FCKeditor\fckconfig.js
The web.config is pointing to the js file in the Custom folder so that's the file you need to modify (FCKConfig.SpellChecker = 'SpellerPages' ; // 'ieSpell' | 'SpellerPages') and (spellCheck="SpellerPages").
I can now get the spell checker dialog to open up but the html doesn't display in it. So I've still got some more to figure out, time to quit for the night and hit it again tomorrow. Hope this helps you.
