WP Statistics: v12.1.3 (latest available via WordPress)
The7 Visual Composer: v5.2.1
Code below is from the page source when using the Visual Composer front-end editor. When WP Statistics is active, the “Save Changes” button does not function (screenshot).
<script type=’text/javascript’ src=’http://www.joshuajohnsondesign.com/wp-content/plugins/wp-statistics/assets/js/Chart.bundle.min.js?ver=2.7.0′></script>
I can confirm it breaks Visual Composter. It also seems to break the page options on the admin screens.
