I've just upgraded our installation of phabricator according to Installation guide.
Everything went well, but now I figured out that I can't edit tasks on project workboard (ticket edit button doesn't work). And I can't create tasks from workboard (column dropdown item). It just seems smth. blocking an ability to follow the link.
A bit later I figured out that if I remove 'data-sigil="column-add-task"' and 'data-sigil="edit-project-card"' from HTML then it'll work.
Thus as a dirty workaround I commented out following lines:
src/applications/project/controller/PhabricatorProjectBoardViewController.php:559 src/applications/project/view/ProjectBoardTaskCard.php:66
and it's working in my setup right now. But maybe there's a better way to fix this
