CKEditor WYSIWYG - Can't use link dialogue to create links (OK button doesn't work)
Try this:

JQuery update settings:
Set alternate jQuery version for admin pages to: 1.5

Make sure CiviCRM theme module is installed

In Appearance -> set CiviCRM Administration theme to Adminimal (or some other Admin theme)

You’ll want admin jquery 1.5 for many admin pages on your drupal site to work well. Here’s a reference: https://www.drupal.org/project/views/issues/1965674
