I have just upgraded from CiviCRM 4.6 to 5.4.1. In events and mailings the description boxes are missing CKEditor. I have tried clearing caches and I have installed I10N for GB as some. I have also looked for the Access CiviCRM permission and that is selected for Events.
I'm stumped and now all our events have raw html in the descriptions. Can anyone help please.
