Tasty Recipes allows your readers to rate your recipes when they leave a comment on a recipe post. However, this functionality only works when the default WordPress comment form is used.
Any plugins, such as Jetpack comments, Disqus, or others, will not work with the default Tasty Recipes ratings. Why? Simply because we can't "hook" the functionality into an unknown area - the only one we know to exist is the default WordPress comment form.
Similarly, if you use a theme that uses a custom comment form instead of the default comment form, the ratings will not be available. To test this, switch your theme over to the Twenty Seventeen theme, which uses the default form, and see if the ratings option appears.
The Good News
If you are using Jetpack comments, you can turn that off to re-enable the default WordPress commenting functionality.
If you want to continue using your comment plugin (Jetpack or Discus), or your theme has a non-standard comment form implementation that prevents the rating from showing up, we offer an integration with the WP-PostRatings plugin to allow readers to leave a rating without leaving a comment.
