I understand your point, the developer is correct but from our side, we are not wrong. If you use our template, you need to use Bootstrap 3, our template always take the advantage of modern technology, Bootstrap 2 is too old, like I mentioned above, it's better if there is option to support both versions. I see lots of extensions support the same. That would be good for customers.
I just helped you to add to small tweak to make the slideshow displays fine on mobile:
@media (max-width: 767px) {
.rscarousel .item .span4.rsmg_center_element {
float: none;
display: block;
width: 100%;
}
.rscarousel .carousel-inner .item .container .carousel-caption h5 {
color: #ffffff;
}
}
