Cannot read property 'options' of undefined ckeditor.js?_dc=1387801326881:627

Hi,

I have the following issue when I try to initialize the editor inline: Cannot read property 'options' of undefined ckeditor.js?_dc=1387801326881:627.

What I did: I have downloaded ckeditor_4.3.1_standard.zip, installed it then I did CKEDITOR.inline('my-editable') and I get the above error.

Any idea?

Thanks,

Iulian
