Summary of the issue you are facing:

When I try to create a shareable link, the nextcloud desktop client tells me Sharing is disabled

I can create sharable links via the web interface

The required permissions in settings appear to be active

[tflidd]

Just for clarification, this is a simple folder in your file structure that you want to share via link?

Not something that was already shared to you, external storage, … etc.?

Reproduce:

• go to you main folder
• create test folder
• try to share this folder via link from desktop client

and with NC 31, this was working for you?

[EazyFreight]

@tflidd

Yeah, it is a file which I uploaded to nextcloud which I was then trying to create a share link for

[tflidd]

With client 3.17.2 on Win11, on NC 32 RC 3 I cannot reproduce the error. I updated the test setup to the latest NC 32, and even then I can create a shared link of a file.

However I cannot unshare….

@tflidd

However I cannot unshare….

This seems to be a bug in the maps app, there is already a bug report:

[Bug]: Maps app fails with "Undefined constant OCP\Share::SHARE_TYPE_USER" on Nextcloud 32

[tflidd]

Did you also check your logs? I suppose for the sharing permissions, the client is sending a query to the server, and if there is an error, this might explain the difference.

[EazyFreight]

@tflidd
the main log seems to be `OCP\HintException: Configuration was not read or initialized correctly, not overwriting /path/to/nextcloud/config/config.php`

As this is a plesk install, the permissions are all set up as owned by plesk

With this being a plesk install, the directory and all contents has the ownership - user psaserv

[tflidd]

Do you know the php user? This user needs at least read access to the config file.

[EazyFreight]

The PHP user is showing the same when I run ps aux | grep php-fpm

[tflidd]

Did you change something in the config file?

[EazyFreight]

@tflidd

No, Until the sharing option stopped working, I had no reason to change anything in the config.

My config.php

$CONFIG = array (
  'passwordsalt' => 'ramdom_salt',
  'secret' => 'random-secret',
  'trusted_domains' => 
  array (
    0 => 'localhost',
    1 => 'nextcloud.domain.com',
    2 => 'server.domain.com',
    3 => '87.xxx.xxx.xxx',
  ),
  'datadirectory' => '/var/www/vhosts/domain.com/.nextcloud/data/f3bc0a18c779',
  'dbtype' => 'mysql',
  'version' => '32.0.0.13',
  'overwrite.cli.url' => 'https://nextcloud.domain.com',
  'dbname' => 'nextcloud_5eb59705',
  'dbhost' => 'localhost:3306',
  'dbport' => '',
  'dbtableprefix' => 'oc_',
  'dbuser' => 'ncuser',
  'dbpassword' => 'password',
  'installed' => true,
  'instanceid' => 'ocrqyjx7bdai',
  'maintenance' => false,
  'theme' => '',
  'loglevel' => 0,
  'mail_smtpmode' => 'smtp',
  'mail_sendmailmode' => 'smtp',
  'mail_smtphost' => 'smtp.smtp.com',
  'mail_smtpport' => '587',
  'mail_from_address' => 'webmaster',
  'mail_domain' => 'domain.com',
  'mail_smtpauth' => 1,
  'mail_smtpname' => 'server',
  'mail_smtppassword' => 'password',
  'mail_smtpsecure' => 'tls',
  'default_phone_region' => '+44',
  'config_is_read_only' => false,
);

I have tried with and without the closing `?>` it makes no difference

[EazyFreight]

Looks like ive solved it

That section seems to ahve been the problem… I turned it on and now it works… I dont know what would have turned it off in the 1st place as I never access the nextcloud web interface. I have no need to.

Is this new since the last update?

[EazyFreight]

@tflidd
I was under the impression that it was sorted andI had just left it be.

I then noticed that, although sheare links were being created, they were not working correctly. when clicking them, there was no file available.
I then logged into nextcloud to check things at my end and this is what I noticed

I dont have a clue what would be causing this error. As you can see, along the top, the files are there but the main file tree isnt working
