The thing is that when you add the /beta to the upgrader.php, you get “Can’t apply upgrade because the following files were modified: inc/classes/BXDoIUpgrader.php”. It is important to note that I took a look at this file earlier and it that “beta”. Upgraded and got: Site was successfully upgraded to 9.0.1. Please go to Studio > Apps Market > Updates to check for modules updates. Seems that the upgrade actually downgraded the install and remi¥oved the “/beta” in that file.
