There is a lot which is wrong!
simply false as value is wrong, since this is not a boolean value:
/**
* This sets the default region for phone numbers on your Nextcloud server,
* using ISO 3166-1 country codes such as ``DE`` for Germany, ``FR`` for France, …
* It is required to allow inserting phone numbers in the user profiles starting
* without the country code (e.g. +49 for Germany).
*
* No default value!
*/
'default_phone_region' => 'GB',
There is a typo ( → a ← mbedded)
this should be
'knowledgebase.embedded' => false,
There are no paths here. Paths must be entered as values in quotes and lines must end with a comma.
There is a typo (coo → c ← kie)
this should be:
'remember_login_cookie_lifetime' => 60*60*24*15,
This is used to close an array of values that has not been opened before, so this closing bracket does not belong there.
That’s what I noticed immediately.
If possible, you shouldn’t edit the config.php directly, but → make the entries with occ as intended ← . This avoids errors like these that were caused by brute force.
If you still have problems with occ, you could try the occ wrapper → nc-occ ← , which builds the commands interactively with you and also works for Nextcloud All-In-One.
h.t.h.
Much and good luck,
