I'm having this error when editing the user profile:
Fatal error: Call to undefined function ckeditor_load_toolbar_options() in /home/mysite/public_html/sites/all/modules/ckeditor/includes/ckeditor.user.inc on line 37
I am also having other problems when creating new content. The CKEditor only appears when you click in "Switch to plain text editor".
There are also other problems with the site content creation I do not know if related to the CKEditor.
For example: the bar to add address friendly is disabled.
The profile in use is full HTML and the dev version is the last, tha was provided today, 3
Sorry to enter more than one problem in this issue, but they only appeared after the latest updates, so I believe they are related.
