Migrated site to similar environment and children not showing for any extras (Collections, Gallery, SocialNetworks, RobotsBuilder etc.) in manager. Same behavior for all extras supposed to display children. The top menu items disappear (reappear when page refreshed) and manager page becomes unscrollable. 2 error messages in the browser’s console:
ext-base.js:21 POST https://DOMAINNAME/assets/components/gallery/connector.php?action=mgr/album/getNodes&id=root 404

The children exist, the front-end is fine.
MODX 2.7.3

logs do not give me anything manager related.
