Unzip the archive and open your FTP client. We’ll need the /wp-content/plugins folder – it’s the path where your plugins are stored.
Drag & drop the Download Disable admin notices individually plugin folder from the default path to the plugins folder on your hosting. Be careful: the Download Disable admin notices individually folder should be moved to another Download Disable admin notices individually folder. If you’ve done everything right, you’ll see a new plugin at the “Installed plugins” page on the dashboard:
Complete the installation by clicking the “Activate” link.
