Arrows in Revolution slider after upgrade

Hello,

1. You need comment the code in parent style.css file to show slider arrows:

.rev_slider_wrapper .tparrows {
  background-image: none;
  width: 45px;
  height: 45px;
  background-color: transparent;
  border-radius: 100%;
  border: 2px solid #fff;
  text-align: center;
  font-size: 0;
  font-style: normal;
  text-indent: 0;
  opacity: 0;
  -webkit-transition: all 0.3s ease-in-out;
  -moz-transition: all 0.3s ease-in-out;
  -ms-transition: all 0.3s ease-in-out;
  -o-transition: all 0.3s ease-in-out;
  transition: all 0.3s ease-in-out;
}
.rev_slider_wrapper .tparrows:before {
  font-family: FontAwesome;
  font-size: 30px;
  position: absolute;
  color: #fff;
  line-height: 41px;
  display: block;
  width: 100%;
  height: 100%;
  -webkit-transition: all 0.2s ease-in-out;
  -moz-transition: all 0.2s ease-in-out;
  -ms-transition: all 0.2s ease-in-out;
  -o-transition: all 0.2s ease-in-out;
  transition: all 0.2s ease-in-out;
}
.rev_slider_wrapper .tparrows:hover {
  background-color: #fff !important;
  opacity: 1;
}
.rev_slider_wrapper .tparrows:hover:before {
  color: #252525 !important;
}
.rev_slider_wrapper .tparrows.tp-leftarrow.default {
  left: -40px !important;
  top: 50% !important;
}
.rev_slider_wrapper .tparrows.tp-leftarrow.default:before {
  content: "\f104";
  left: -1px;
}
.rev_slider_wrapper .tparrows.tp-rightarrow.default {
  right: -40px !important;
  top: 50% !important;
}
.rev_slider_wrapper .tparrows.tp-rightarrow.default:before {
  content: "\f105";
  right: -1px;
}
.rev_slider_wrapper:hover .tparrows {
  opacity: 1;
}
.rev_slider_wrapper:hover .tp-leftarrow.default {
  left: 40px !important;
}
.rev_slider_wrapper:hover .tp-rightarrow.default {
  right: 40px !important;
}

2. Add this code in Theme Options > Custom CSS > Custom CSS for desktop:

.carousel-area .owl-controls .owl-next {
   right: -20px;
}
.carousel-area .owl-controls .owl-prev {
   left: -20px;
}

3. Please check the description of our theme update:
http://themeforest.net/item/woopress-responsive-ecommerce-wordpress-theme/9751050
Pay attention to the files that were deleted:
DELETED : woopress/woocommerce/order/order-details.php
DELETED : woopress/woocommerce/myaccount/my-orders.php
You must delete them from your theme folder too (in wp-content/themes/woopress/woocommerce directory).

Best regards,
Jack Richardson.

Same problem here.
1. I checked the code and its the same. (I never touched it)
2. Added code to custom css.
3. Those files do not exist in my directory.

Still only have rectangles in my slider… What did I do wrong?
