Any WordPress commercial (or paid) plugins require that you install them manually via File Transfer Protocol, for example. This process isn’t as simple as installing a free plugin, but WordPress will let you do what you need to do.

Follow these steps to install a plugin via FTP in your WordPress installation:

  1. Download the plugin from the source to your computer.

    Commercial plugin developers provide you with links that you can click to download the plugin files — usually, in a Zip file.

  2. After you download the plugin to your computer, if it’s in a compressed Zip file, unzip it to access the uncompressed files.

    If the file is zipped (compressed), use a free web application (such as WinZip) to unzip the plugin.

  3. Connect to your server using your preferred FTP application.

  4. Navigate to the wp-content folder within the WordPress installation for your website.

  5. In the wp-content directory, find the plugins directory; upload your plugin to this location via FTP.

    Congratulations — your plugin is installed, but you still need to activate it.

  6. Choose Plugins→Plugins on your Dashboard.

    The Installing Plugin page appears.

  7. Click the Activate link that appears below the plugin’s title.
