Comments

p.s. It gone because I disable content view so it is my mistake? in drupal 7 it works.

It is better to separate core views and custom.
And way I can't configure custom block from block tab.(no configure link on right side)

Status:Active» Postponed (maintainer needs more info)

Is this an existing installation? There was a recent change that caused this for me too but a re-install solved the problem.

Priority:Critical» Normal

Dropping from critical to normal until we get more info.
