So i upgrade from 1.38a to 1.54..upgrade database and now add ckeditor ,made choice via Admin->Configuration->My Store->HTML Editor
If I now select at Text Editor the CKEditor from dropdown it shows the CKEditor choice but then jumps back to Plain Text.
Not any logs about this. Cant this happened because i used 1.38a before uprgade. ? Yes i made fresh install to 1.54.
