Updating to the WordPress Social Sharing Optimization (WPSSO) Pro version is simple and easy — click on the “Purchase the Pro Version” button on any WPSSO settings page. After your purchase, an email will be sent to you with an Authentication ID and installation instructions.

The WordPress Social Sharing Optimization (WPSSO) plugin and its extensions use the WPSSO Pro Update Manager (WPSSO UM) free extension plugin to check for Pro version updates. If you haven’t already installed the WPSSO UM extension, please see the WPSSO UM download and installation instructions here.

Once the WPSSO UM extension has been installed and activated, enter the unique Authentication ID on the SSO > Pro Licenses settings page. After saving the changes, an update for WordPress Social Sharing Optimization (WPSSO) will appear on the WordPress Dashboard > Updates page. To install and activate the new Pro version, update the plugin from within WordPress (as you would any other plugin).

If you use a WordPress multisite configuration, enter the Authentication ID either on the Network SSO > Pro Licenses settings page (to license several sites at once), and/or in the individual site / blog SSO settings. Note that the default site / blog must be licensed to allow Pro version updates from the Network admin interface.
