Hi,
splitbrain opened a new pull request at
https://github.com/splitbrain/dokuwiki/pull/3817:
When a plugin used an array setting and was then installed, the old
configuration can remain in local.php. It is handled by the SettingUndefined
class. However this class used the base out() mechanism which didn't know about
arrays. The result was a fatal error resulting in a completely empty config
file.
This moves the error handling from the SettingArray class to the base class
which fixes the original problem.
It also adds a check if the Writer is about to write a completely empty config
file and refuses to do so, throwing an Exception.
Probably related to #3777
