that is correct neilo, I clarified this in the readme file available in the download center by adding the following note:
NOTE: This fix is only needed for PowerCMS 2.1.0 and below. To determine if the fix is needed, look for the following file:
HTMLEditor/editor/plugins/kfm/configuration.php
If it does not exist, you are using version 2.1.1 and do not need to apply this fix.
