Begin of the insertionAfter deb package upgrade from 6.1.6 (stable/6) to 7.1.0 (stable/7) workpackages list is not showing up in IE 11 (11.0.9600.18665) at http://openproject/projects/demo-project/work\_packages (intranet link). It works in Chrome (59.0.3071.115). You can see existing tasks in summary (atatched op\_wp\_summary.png). I cannot modify view and filters, as they are not displayed (attached op\_wp\_list.png).

I know IE is not supported but I can still see WP list in IE11 on your site https://community.openproject.com/projects/openproject/work\_packages?query\_id=491 (attached wp\_list\_at\_community.openproject.com.png).
