Hi, I noticed that de Day of week control in the backend interface for weekly events didn´t work anymore. The Chromium debugger showed a version conflict between Bootstrap 3.3.6 and jQuery 3.0.1. I fixed this by setting the CDN to load Bootstrap 3.3.7. It seems to me that de default should be changed (to Bootstrap 4 if possible...), but at least I found a work-around.
