I recently set up Phabricator for a personal project.
I've just created my first task, and when I go to /T1 it shows me
>>> UNRECOVERABLE FATAL ERROR <<< Call to undefined method PhabricatorActionListView::setDisabled() /opt/phabricator/src/applications/maniphest/controller/ManiphestTaskDetailController.php:422 ┻━┻ ︵ ¯\_(ツ)_/¯ ︵ ┻━┻
My phabricator/ checkout is at 0e8ed0c61684441ceafe2791b9a05970b58babac.
