This tutorial will guide you how to manually install a WordPress plugin ZIP file via FTP.
Step 1: Extract the WordPress plugin ZIP file to a folder on your computer.
Step 2: With your FTP software, upload the extracted Plugin folder to the
wp-content/plugins folder in your WordPress FTP server.
* When a ZIP file is extracted, some unzip software may add a parent folder outside of the Plugin folder. Please make sure you have uploaded the Plugin folder, not this parent folder.
Step 3: Log into your WordPress backend, left menu, Plugins -> Installed Plugins, find the plugin from the list and click
Activate to activate it.
