==================
Hi,

yesterday I bought a new comfortupdate license and upgraded to 3.28.63+230628. Today, I tried to upgrade to 5.6.28 but unfortunately everytime I initiate the upgrade process, I am signed out of limesurvey as soon as I try to reach the file system step. I know that I am being singed out because when it tries to load the file system step, it's starting to show an empty screen but when I hover over that space, I can click on it and input my credentials. If I sign in through the blank space, I get an error stating that Limesurvey could not determine the version number.

Is there a way to solve this?
Thanks!
