Issue [Solved] Post Rating reset restriction

@injanebhamed,

Please use the hook code below:

add_action('init', 'resrict_post_ratings_reset');

function resrict_post_ratings_reset() {
    $user = wp_get_current_user();

    if (!$user || empty($user->roles) || !is_array($user->roles)) {
        return;
    }

    $wpdiscuz = wpDiscuz();

    if (!$wpdiscuz) {
        return;
    }

    if (in_array('author', $user->roles)) {
        remove_action('add_meta_boxes', [$wpdiscuz->helper, 'addRatingResetButton'], 10);
    }
}

Using the same logic you make for other user roles:

if (in_array('author', $user->roles)) {

Put the hook code in the WordPress active theme functions.php file: https://www.wpbeginner.com/plugins/how-to-easily-add-custom-code-in-wordpress-without-breaking-your-site/
