Unexpected error

I don’t use property post_type in my snippets. Maybe it is a conflict with the theme…

In line 80 I have this line:
$post_type = ! empty( $post ) ? $post->post_type : get_post( $data->ID )->post_type;

I don’t use the last version of the plugin and I cannot update because I use a version with my own customizations and I have done this post in order to help you.

I love your plugin and it would be my pleasure to contribute =D

In line 80 I have this line:
$post_type = ! empty( $post ) ? $post->post_type : get_post( $data->ID )->post_type;

The problem in this line was that $post could be an integer=post_id, so the so simple fix is this:
$post_type = ! empty( $post ) && is_object($post) ? $post->post_type : get_post( $data->ID )->post_type;
