Hi!
Thank you for the detailed ticket. I think I have figured it out: the slick and slide div cannot handle the rtl direction, so it needs to force the ltr instead and it will work. Put the following CSS code to the Custom CSS field on the plugins Theme Options panel (http://i.imgur.com/kU3C89A.png):
[html]
.rpp_slick {
direction: ltr;
}
