First, my website is on last version of WordPress, your plugin and WooCommerce.
I tried the plugin on my private website and show me a PHP fatal error on activation about woocommerce comments.
public function filter_wp_count_comments( $comments, $post_id ) {
// if this is grabbing all the comments, filter out the 'post' comments.
if( 0 == $post_id )
$comments = $this->get_comment_counts();
// If we filtered it above, it needs to be an object, not an array.
if( ! empty( $comments ) ) {
$comments = (object) $comments;
}
return $comments;
}
It bugs in the casting operation (array to object).
