I followed the instructions and clicked the update button in studio dashboard to upgrade. Then I went to edit the Edit file inc/classes/BxDolUpgrader.php, it says "protected $_sUrlVersionCheck = 'https://v.una.io/beta/';" but I didn't change anything. In the instructions, it says to change it to "protected $_sUrlVersionCheck = '_https://v.una.io/beta/';".

Notice that there is a "_" before https. Do I need to include the "_" before https? Because I am still seeing the update button in the dashboard.
