Upload through WordPress admin
In WordPress, open Plugins, choose Add New, then Upload Plugin. Select the ZIP file, install it and activate it after WordPress confirms the package is valid.
Check for nested ZIP files
Some product packages contain documentation, child themes or multiple installable ZIP files. If WordPress says the package is invalid, open the archive and look for the actual installable plugin ZIP inside.
Keep a backup
Before replacing a production plugin, back up the site and database. Test updates on staging when possible, especially for WooCommerce, membership and page builder plugins.

FAQ
Why does WordPress say the package could not be installed?
The archive may contain another ZIP inside it, or it may be a theme instead of a plugin. Extract the package locally and look for the installable file.
Should I update directly on a live site?
For important sites, use staging first. GPL files can still conflict with themes, PHP versions or other plugins.
