Can not Work in Bootstarp 3.3.1(New 2014.11)

[thribiere]

Hi, dont work with Bootstrap v3.3.1 because of 'hide' class : in 3.2.0 hide is "display:none !important" instead of "display:none"
Temp fix for me : no hide class and a style added :
<div id="myLightbox" class="lightbox fade" tabindex="-1" role="dialog" aria-hidden="true" style="display:none;">
