Upload the ZIP file with WordPress (Dashboard > Plugins > Installed Plugins > “Add New” button > “Upload Plugin” button >) or copy it to your plugin folder ([your-wp-installation]/wp-content/plugins/term-and-category-based-posts-widget) to your wordpress installation.
How to activate the widget
In the admin panel Plugins > Installed Plugins > Term and Category Based Posts Widget is an action link License below the widget name. Click this and you come to the Licens activation admin panel.
In the License activation panel you have to enter your license key and Save Changes button. Up to now your widget is activated and is visible placeble to your widget areas or as shortcode to the content.
If you want to deactivate the license, for example in order to move it to another site, submit an empty value as the license key.
License transfer between sites
Sometimes when going from development to production the domain of the site changes and if you’re not going to keep a live development server, it doesn’t make any sense for both the user or us to make the user buy two licenses just for that.
With Term and Category based Posts Widget v4.7 and heigher you’ll be able to just deactivate the license on your development site and activate it on production.
