GD Star Rating not working

In case you are not able to run the  GD Star Rating plugin with WP Rocket, you will have to exclude a CSS file from minification.

In WP Rocket→File optimization→CSS files, exclude the following file:

/wp-content/plugins/gd-star-rating/css/gdsr.css

In case the issue is not resolved, you can try to turn off minification (JS and CSS) completely and follow this guide:
