Hello !
I have the same issue with Academi (Moodle 2.8). I don't know why this theme only runs in Firefox and Chrome but not in IE 11. It seems to have something wrong with Bootstrap.
Ex: When i browse my website in Firefox, carousel javascript can not automatically run the slides, i have to click to the slide button for the first times and then slideshows may continue running (must click for the first time, not auto run). While browsing on IE11, it absolutely keep silent.
I've followed Mary's steps above in this discussion but still not fix this bug. How could i do to solve it ?
Thanks in advance.
