Upgrading the YourSites Client Plugin
Since the YourSites client plugin is unique to each combination of server and client site it cannot be currently be updated using the Joomla updater.
If you upgrade YourSites and need to update the client plugins.
You can do this from the list of sites in YourSites. Select all your sites and click the 'YourSites -> Upgrade YourSites' button or click the plugin version icon on a site by site basis.
