Hi,
If found the solution from fckeditor's website forums. Here is the solution if someone faces the same problem,
open following file,
<<your_web_root>>/opengoo/public/assets/javascript/fckeditor/fckconfig.js
Change this,
FCKConfig.SpellChecker = 'SpellerPages' ; // 'ieSpell' | 'SpellerPages'
FCKConfig.SpellerPagesServerScript = 'server-scripts/spellchecker.php' ; // Available extension: .php .cfm .pl
then,
open following file,
<<your_web_root>>/opengoo/public/assets/javascript/fckeditor/editor/dialog/fck_spellerpages/spellerpages/server-scripts/spellchecker.php
Change this,
//$aspell_prog = '"C:\Program Files\Aspell\bin\aspell.exe"'; // by FredCK (for Windows)
$aspell_prog = 'aspell';
// by FredCK (for Linux)
And your are done,
Yes one more thing, do not forget to refresh your web browser.
Rgds,
Nimesh
