For the Normal Slider, there really isn't a way to do that. You could replace this file with the color png that you choose.

wp-content/plugins/wp-review-slider-pro/public/css/imgs/slider_arrow.png

The slide dots are a little easier. Just add this to the custom CSS for the slider.

.wprs_unslider-nav ol li {
border: 1px solid #cc1818;
}

.wprs_unslider-nav ol li.wprs_unslider-active {
background: #cc181885;
}

The Advanced Slider is also pretty difficult. It uses a special font to display the arrow so there really isn't an easy way to do it.

You can change the dots like so...

.slickwprev-dots li button:before {
color: red;
}

.slickwprev-dots li.slickwprev-active button:before {
color: red;
}

That means that the previous scrape job was unable to complete so you can't use the "only scrape new reviews" option. The invalid url message means that the google search terms are not specific enough. Here is more info...

I'll have to look when I get back in town. Currently, only the Admin and Editor can see the Review List.

This is the code that is used to check....

// check user capabilities
if (!current_user_can('edit_pages')) {
return;
}

What member plugin are you talking about?

The latest version of the plugin does allow the Editor role to manage the review list.

Are you still having issues? They look okay to me. It could be a caching issue or a CSS minimization plugin.

The plugin can't automatically download the photo. Facebook doesn't make it available in their API. You can manually add it after the fact. You can use the pencil icon on the left side of the review on the Review List page. Then look for the Review Media setting on the pop-up.

The easiest way to do this is to first input one manual review using the button on the Review List page. Then use the "Download CSV File of Reviews" and open it in a spreadsheet program on your computer. Then you can copy/paste reviews into that file using the one review currently in the file as a template. Then use the "Import Reviews" button to import it back in.
