I have pages which are nested in 3 levels, i.e:
As you can see the permalink gets quite long. If I go to the TinyMCE editor, write festival name and try to add a link on it to direct to that festival page, I get such generated link (notice three dots):
And the link does not work, it directs to 404 page. If I update the link with the correct, it saves well.
Actually I cannot repeat this behavior all the time. Sometimes this works just fine from the beggining. Any ideas what can couse this?
