Thank you for your instructions. I've done all that, and uploaded the new ckeditor folder to the website but it's still a problem.
So I'm guessing I need to do something in the page's code? But if I select the section of ckeditor code which will give me access to the HTML editor in the Properties tab, I get a warning that I'm making changes to code not marked as editable and they will be lost next time I make template changes. I don't care so much about that, but I'm concerned if that's okay. I also noticed that Editor Present field is Sally 1 (custom) and I can't find that in the old ckeditor folder to copy. Again, I don't mind losing that and just picking something else. But I don't want to make changes to these forms that might mess them up.
So I want to check with you about how to proceed implementing the new editor once I've downloaded the new files and then copied them up to the website.
Thanks.
