Error - Enable at least one style, otherwise disable the Style plugin.

This error occurs when you have the 'Style' dropdown (provided by core) enabled, but have no styles configured for it to display. It's not related to the ckeditor_link_styles module.

Perhaps all your previous styles were for links and have been moved to the 'Link styles' field? If that is the case, you just need to drag the 'Style' button out of your active toolbar config.
