Sometimes, even after you have added the code for the slider widget in your theme file, you see only the arrows on your site, and not the reviews.

This is usually due to the color of the review text blending with the background color of your site. Follow this steps to correct it;

  1. In your account, go to Customize Widgets, then go to Slider Widgets

2. Go to the Style settings and change the color to a more visible one. Then save your work

3. Go back to your site and reload the page. You slider reviews should be visible now.
