Yes, now its works in need set i to 7.4 then re-run update process and page in now available. Also after that i notice that hosting provider bring php 8. Works nice.
I assume config.php is red, it would be good to change chmod to 444 (not writable). There is nothing wrong with that, but for better security it is recommended to change it.
If it's a folder, change chmod 777 or 755 (writable)
