Technote Details :: Error when performing spellcheck in KTML
Issue
After adding the KTML editor to one of my pages, when I try to spellcheck my content using the built-in spellchecker, I get an error message:
The aspell library was not detected on the server. Please install aspell in order to be able to use the KTML spellchecker. Error returned:

Reason
This happens because KTML uses the aspell program to provide spellchecking services. When you click on the spellcheck button in the KTML interface, it will attempt to execute the aspell file defined in the KTML configuration. If you do not have aspell installed on the server serving the pages, the error will be displayed.
Solution
To solve this issue you must make sure that
aspell is installed on the server and the correct path to the executable is specified in the KTML configuration. You can download the aspell main program
here, and language dictionaries
here.
