User roles and permissions are something that is very important when you have a blog or website that you want to run effectively. This also ensures that you have a specialized team for every category that you have and would want to handle every category effectively and effortlessly.
All these different roles have different kind of things that they are allowed to do and the permissions to use the blog the way they like is very different from each other. Where the Administrator is the top most level of permission, the subscriber is only allowed to view and surf through the blog, not making any changes into it.
The Administrator can install, edit and delete everything they want. Be it plug ins, themes, posts or pages. The administrator has the privilege to do anything they want with the blog. They become joint owners of the blog.
The Editor is the second in the list. They can only add, edit, publish or delete any kind of posts on the site and not do anything more than that. They come second to the administrator and have almost all the features that the administrator has.
The main difference between the editor and the author of the blog or website is that the author cannot add categories to their post and have to choose from the categories that already exist.
As far as the contributor is concerned, they can only add new posts and edit the posts written by them only. Publishing rights aren’t given to them and neither the rights to add pictures to their post is given. The subscriber, at the end only can view the posts.
