    Hi there, Im getting this warning on my WordPress dashboard every time I access to any post. I’m using wp-gallery-metabox only in one custom post type, but getting this warning in all post.

    Warning: in_array() expects parameter 2 to be array, boolean given in …/wp-gallery-metabox/admin/class-wp-gallery-metabox-admin.php on line 67

    Any help?
