It looks like instance administrators can get 404 errors by:
- Go to phabricator.mycompany.com/settings/;
- Select Edit Queries (/settings/list/query/edit/) or Advanced Search (/settings/list/query/advanced/) in the sidebar;
- See 404 error
Noticed this on our install and reproduced on a new Phacility test instance with:
