Ok, this is now bugging me.
Went into site, removed some images from the page, added some more, saved, exited. Went back, guess what no ckeditor......
Cleaned out all caches, re-installed java, no joy.
I can use the demo ckeditor on the ckeditor site, but not the processwire demo version or the site I am working on, but I can use this forum which I think uses ckeditor
Can anyone help me solve this?
