After upgrading to 7.1.11 - ckeditor no longer shows up and there are 2 uncaught exceptions. The above is the first one - the other is:
uncaught exception: [CKEDITOR.editor] The instance "edit-body-und-0-value" already exists. This error seems to be resolved by dis-abling the wysiwyg module - though they worked well together in 7.1.9
I use thelibaraies module and the ckeditor itself is installed in the libraries directory.
This was working fine in 7.1.9
