After you have downloaded the add-on, visit your UD Account. You will find download links for your products. Download them to your computer and Upload as new plugin on your site. See screenshots below.
Then activate installed plugins. You will see such warning for plugin you are trying to activate...
That means that you need to activate license key or you won't get updates and you always will see that warning. It will disappear when you will put license key for your product in Add-on tab where the link should take you.
On the Licenses admin screen, you should see all your installed products, with an option to add your license key for product.
To add a license key:
Once you have activated your product, you’ll be able to update your product via the Dashboard > Updates admin screen.
To update your product:
Products do not have the limit of usage. License gives you the ability to update add-on or theme within one year after download. You will still have the ability to use a product after one year expired, but updates won’t be available anymore. To receive updates after one year expired you will need to redownload the product.
Please also note that we do not support our products if the code was customized directly. After update you will lose your plugin customization. If you need to customize some template in our plugin, you will need to copy the template to the root theme/child theme folder and only there customize it.
Each add-on you can use on two sites. So if you need to test between staging and production it’s simple. You can also easily move licenses from site to site. To deactivate your license key and reactivate it for another site please go to your Account Dashboard > UD Account page.
From here you can ‘deactivate’ your license key:
Then you can reactivate the same license by going to your other WordPress site’s Dashboard where it says WP-Property Licenses, and copy and paste your license and hit enter. Follow the steps above for Adding Licenses if needed.
