(don't kill me, I didn't know that it's frowned upon)
I am not sure if this is the place to ask for help, so tell me if it's not (and maybe where to ask).
I am trying to update to the latest Grav release 1.7.29 from (originally 1.6.24, while troubleshooting today updated to) 1.6.31 (using direct-install.
I tried updating with self-upgrade and direct-install <latestVersionURL>.
But, while trying to install, it gives me the following error:
Installing upgrade... [30-Jan-2022 17:04:37 Europe/Cityxy] PHP Fatal error: Uncaught Error: Call to undefined method Grav\Common\Utils::basename() in /var/www/virtual/name/html/tmp/Grav-61f6b713f0bb9/zip/grav-update/system/src/Grav/Installer/VersionUpdate.php:29

From my understanding the files between versions have been changed, and looking at the Grav documentation, the called method basenames() is now in Grav/Common/URI, not in Grav/Common/Utils.
So I assume I located the problem, but have no idea on fixing it. Since I am not very well versed on this whole topic of managing websites (never set up the site, only maintaining it), I would really appreciate a safe answer on how to update Grav to the newest version which doesn't risk me destroying the functioning of the website.
Thank you for helping! :)
