No matter what I do, I cannot get links to headers on the same page to work. Same is true for links to anchors. I can enter the values in Link dialog, but the resulting link does not allow me to go actually go anywhere. The only available fields in edit more are "Edit" and "Unlink". The "Go To Link" button is grayed out.
Also, typing "[" in the editor field gives me an error rather than showing possible link candidates. The error is
The markup provided is not valid link markup
Is there some configuration or permission needed in order to create intra page links?
