You should now see a screen with the list of plugins that are installed on your system. At the top left is a button labelled Upload Plugin. Click on it.
You should see a dialog box asking for the plugin file. Navigate to your desktop and choose the file you downloaded in the first step of this procedure then click the Open button at the bottom of the dialog box
You should now be back in the main Add plugin screen with the filename filled out. Just click the Install Now button.
If all goes well you will see a new screen with a link that says Activate Plugin. Click on it. That will complete the plugin installation process.
After installation there should be an FAQ page automatically created with the default FAQ add-on shortcode in it. All you need to do is add it to your menu in order to display it to your users on the front-end of your WordPress site.
If you get a “directory already exists” error message, you will need to use FTP to upload the updated plugin to the folder that already exists. Check with your hosting provider for instructions on how to use FTP to upload files. Please make sure you “unzip” the plugin files before uploading them via FTP
