With regard to the HTMLEditor3 images folder path, the webassist/kfm/configuration.php had the paths as:
$kfm_userfiles_address = '../../htmleditor3/files';which I changed to:
$kfm_userfiles_output = 'htmleditor3/files/';
$kfm_userfiles_address = '../../htmleditor3/files';It is now working. I would be interested for any insight as to why this might have happened, and as to why the site settings do not 'take'. i.e: what was my mistake?
$kfm_userfiles_output = 'files/';
Edit: The testing server settings seem to be OK to me too
