Patron Plugin Pro will notice you if any upgrades are available. Clicking on the link in the update notice should automatically update the plugin. This requires you to have a valid license and have saved this license in the Addons tab of your Patron Plugin Pro plugin admin page. Otherwise updates will fail by saying ‘A valid Download url was not provided’.
In case you don’t see the update notice, you can check and upgrade from your WordPress plugin manager.
If that also fails for any reason, you can download Patron Plugin Pro from your CodeBard account here, deactivate/delete existing Patron Plugin Pro, and upload and activate the zip file you downloaded.
If any plugins that are part of Patron Pro package need to be upgraded, Patron Pro will warn you in your WordPress admin. Clicking the notification button will take you to the Wizard, which will automatically configure/update necessary plugins for you.
