wpDiscuz 7 comes with two post rating options. First is a stand-alone post rating system, located under post content and above comment section with rating buttons. You just click on rating stars and rate articles.
Second is based on rating custom fields in comment form. If you’ve already configured the second type (Rating comment field) in comment form, the first type will be automatically disabled. You can enable the first rating type in Comment Form Settings.
In case you want to say thank you! 🙂 We'd really appreciate if you leave a good review on the plugin page. This is the best way to say thank you to this project and the support team.
