Define your license key in your wp-config.php

Instead of entering a license key in the settings page, it’s possible to define the license in the  wp-config.php file. This might be useful when you have a developer license and want to automatically activate Admin Columns Pro for every site you create.

  1. Add the following code in your wp-config file.  define( 'ACP_LICENCE', 'YOUR KEY HERE' );

  2. Your license validation will be done periodically, but you can force this process by clicking the Check license button on the settings page.

Keep in mind that if you move from another (staging/development/accept) environment to the production environment, it may lead to unexpected behavior. A license check is done periodically and it checks for the requesting domain, so when this somehow changed, automatic updates and integration downloads are not available because of an invalid domain/license validation. Then you need to visit the settings tab and re-activate your license.
