I have just updated the ckeditor code in several different drupal sites to 3.6.2 and to 1.8
In all these sites the teaser break has disappeared. I have tried clearing the cache and several other things but nothing has worked to bring the teaser break icons back.
This issue has occurred before, several versions earlier. I do not understand why it is still occurring and, what's worse, I cannot fix it.
I cannot find anyplace in the code where the plugins for the teaser breaks are actually loaded. Of course, there's lots of code so I may just not know where to look.
Any help is appreciated.
