After going through a close inspection it seems like the your plugin is not compatible with ACF (Advanced Custom Fields) if we deactivate ACF plugin data start showing in the Admin area….. Can you pls look into it and fix the compatibility issues?
@hardeepasrani I updated the plugin and I can confirm I am still facing the same issue… front-end loading the review data on the backend all the data is gone… I can see the Review Plugin meta box but there is no data when I activate the box.
