STOP working on WP 4.2.2

Hi, just ran into the same problem when upgrading to 3.3.4. The slider completely disappeared. After much troubleshooting we finally figured out it was due to a change in the plugin’s CSS.

Before upgrading we had in our CSS the following code so that the height would adjust since we had the slider on a responsive website.
.promo_slider { height: auto !important; }

After upgrading this was causing the slider to disappear, but removing it caused a huge gap below the slider as the screen size got smaller.

So the solution was to leave that code in place and add the following:
.promo_slider .panel.current { position:relative; }

Not sure if this is the same problem you were both experiencing, but I hope this will be helpful to someone.

EDIT: Also, regardless of using the height:auto trick, if you don’t have a height set on .promo_slider either in the shortcode or somewhere in your css then you will probably end up with this same problem. The fix should be the same.
