There are 3 different ways to install a plugin in WordPress – automatically from the Plugins repository, uploading through WordPress, and manually uploading via FTP. This post is going to cover how to install a plugin by uploading it from with WordPress. This post assumes that you have already downloaded the Plugin ZIP file to your computer. If you haven’t already done so, do that now and take note of where you save the ZIP file on the computer. DO NOT unzip the file – you will need to be able to upload the Plugin as one file.
To start, hover over the Plugins button on the left-side nav, and then select Add New from the fly-out menu.
From the Plugins main screen, select Upload at the top to go to the Plugin upload page.
Use the Browse button to navigate to where the ZIP file for the Plugin is saved on your computer. Click on the Open button to select the file, and then click Install Now.
Once the Plugin is finished installing, click on the Activate Plugin button to make the Plugin ready to use.
For further help using your plugin, check the Plugin page and see if your plugin includes additional information in the description on how to use it.
