Installation
First, download Block Control from WordPress.org:
Installation through the backend
You can uploaded the downloaded .zip file directly in your WordPress backend. You will need a user account with administrator permissions (or super administrator permissions in multisite installations). As soon as you’re logged in, you can find the entry Plugins > Install in the menu. You can upload the .zip file on this page by clicking on the button “Upload plugin” alongside the headline.
Installation through FTP
To install the downloaded .zip file through (S)FTP, you first need to extract it and upload the files and folders with an FTP program of your choice onto your website.
After the upload, they should be found in wp-content/plugins/block-control.
