hello
we recently upgraded our moodle from 3.1 to 3.3.1.
our course becomes unable to edit (it becomes unclickable) after we configure a week section as hidden from students. we can't add resources , assignments and do such things in mentioned courses unless we unhide the week or delete it.
is this some kind of known gui bug ? any solution to this problem ?
( please do not suggest disabling ajax from the config menu )
thank you in advance
