Why the following warning is shown when trying to use some functions of WP Toolkit?
PLESK_WARN: This feature is not available in the free version of WP Toolkit. To access this feature, upgrade your Plesk license to get the full version of WP Toolkit.
Note: The Plesk Edition is Web Admin.
By default, the Web Admin edition comes with the WP Toolkit SE version, which does not include all features of the extension (such as cloning, staging, etc).
