System Upgrade #8078open
It looks like we need to do some housekeeping regarding CommentPress as we have, in effect, multiple versions activated because of how the theme/plugin has grown and changed its name along with updates.
In the past, you would activate the CommentPress theme and then also activate certain CommentPress plugins to make CommentPress work. Now, you simply activate the CommentPress Core plugin (https://wordpress.org/plugins/commentpress-core/), which has a theme embedded. That means that we need to remove the out-of-date CommentPress theme, as well as these two CommentPress plugins: Commentpress Ajaxified, CommentPress
I have looked into these two CommentPress plugins on our GitHub install and verified that both were updated 6 years ago (cp-ajax-comments, commentpress), which verifies that they are just as outdated as the CommentPress theme (also updated 6 years ago). https://github.com/cuny-academic-commons/cac/tree/1.10.x/wp-content/plugins
Additionally, we should update the CommentPress Core plugin. We are at version 3.9.3, but the most recent version is 3.4: http://futureofthebook.org/commentpress/download/
