There is a chance that I need to rearrange the WordPress of a site and I don’t know how. But I found a WordPress plugin that can be use to rearrange the Post or even your Custom Post Type.
First thing to do is to install and activate the Post Types Order plugin. You can download it for free. Download Post Types Order Plugin. Upon activation, you should notice a new tab under Settings » Post Types Order.
Navigate to Posts » Re-Order. This is where you can freely change the order by dragging and drop whatever post you want to reorder.
