When i upgraded my Talend tool, the connection list is empty. but i already configured the connections. And i can't add a new connection configuration, because there is no that button. you can see the pictures.
Can you resize the create connection dialog? The + button is below the Connections list box. Something definitely wrong if it does not appear, and I will suggest reach out to our support.
