I am getting the same issue after I have updated to wordpress 4.9. And I am getting this error.

Uncaught (in promise) TypeError: Cannot read property ‘getNotificationManagerImpl’ of undefined

at k (tinymce.min.js?ver=4607-20171116:28)

No cache plugin, every morning the same error keeps appearing. But I figured a way to solve it. which seems to be working and it has nothing to do with going through the dashboard and changing the calendar theme.

Thank you for your response, I have a better way to solve this issue.

This issue has occurred to me with one of my site https://commonground.co.za/ . changing the calendar theme works but then breaks after a day or 2, is there a way we can fix it permanently?
