Ckeditor version and language
Thanks Ray,
In case it is useful to someone, it works by copying / pasting the "full" package of ckeditor by performing the following steps:
1- Download the "full" package WITHOUT EasyImage.
In case of selecting Easy Image, the button to insert image disappears.
2- Copy paste of the content in the cdeditor directory without deleting anything that exists.
3- In my case I had to rename the ckfinder directory to kfm again. Otherwise it didn't work.
Cheers!
