Hi @Just4Link - These seem to be two distinct matters. Can you please re-submit the calendar related matter as a separate issue? If you want your issues to be looked at, each needs to be focused on one matter at a time. :)

Let's keep this one focused on the "protocol page" matter.

Can you clarify what you mean by "protocol page"?

Lastly:

"memcache.locking": "\\OC\\Memcache\\APCu",

I would not use APCu for locking. I'd either comment this line out or use Redis. For further questions on this, refer to the documentation and/or the Nextcloud Help Forum - https://help.nextcloud.com

Community Docker image

Your configuration suggests this is not the community Docker image. If I was to guess, you're using the LinuxServer.io image.

Can you clarify what you mean by "protocol page"?

I think this:
#42387

jakobroehrl · 2023-12-20T08:53:06Z

You can fix the protocol page with this: nextcloud/forms#1838 (comment)

Just4Link · 2023-12-20T13:46:17Z

To the memcache: this instance is a fresh setup and redis was not integrated to that point. I set this instance up as a fresh installation because on my productive instance i have the same problems.

Protocol: i mean the logging page in the administration settings.

Calendar: this error is spamming the log since the instance is runnung with my holiday calendar subscription as described above:

Edit: i manged to get rid of it but .... when i browse to the logging page i can see the header of the table and the error: "Could not load log entries" appears top right ... after 10 secs of waiting the page gets populated. 80% better but a little bit annoying

Just4Link · 2023-12-21T16:27:07Z

just a quick info ....
i set up a new instance with the original docker container instead from linuxserver.io.
The logging page seems to work fine there.

The only problem left is the issue with the subscribed calendars where no events shown up.

nursoda · 2023-12-23T16:27:27Z

Please create a separate issue for the calendar issue. Let's focus on the log issue here.

I also experience the "empty log page" along with a notification "Could not load log entries" on NC 28.0.1. Log entries do appear after 10 seconds as described above.

I'm not using an image, or LinuxServer.io: I'm on a long standing custom setup on a local machine, installed myself from scratch on Arch, using PHP-FPM, NGINX, Mariadb, Redis and the NC web installer, updating via zip extraction and occ update. The issue is there even after the NC27+ NGINX site template has been applied.

I'm using Redis for locking, so, while it might be a good idea not to use APCu for locking, the suggestion in the first answer seems unrelated to this issue:

  'memcache.local' => '\\OC\\Memcache\\APCu',
  'memcache.distributed' => '\\OC\\Memcache\\Redis',
  'memcache.locking' => '\\OC\\Memcache\\Redis',
  'redis' => 
  array (
    'host' => '/run/redis.sock',
    'port' => 0,
    'dbindex' => 1,
    'timeout' => 1.5,
  ),

The issue started with NC28, never happened with NC <28. It happens on my bare minimal test instance (without forms), on my test-all-apps instance as well as on production instances.

@devs What tests/logs/configs do you need to help fix it?
