IE 11 Discussion post not appearing correctly on GPS Group

From an email send to Todd from Bob from Dominique dated June 4.

The second item is related to the last issue I reported to you with the a new posted Discussion not appearing correctly for one of our users. She is using IE11 on a Windows Home Premium machine and when she attempts to add a new discussion topic, they do not appear on the discussions tab. If you click on the link to the discussion from the “Recent Group Activity” section, the site displays an xwiki page for editing (for admins) or an “Access Privileges Required” error message for other users.
