Getting help
In order to help you as efficiently (and quickly!) as possible, please fill in as much of the below requested information as you can.
Before clicking submit: Please check if your query is already addressed via the following resources:
- Official documentation (searchable and regularly updated)
- How to topics and FAQs
- Forum search
(Utilizing these existing resources is typically faster. It also helps reduce the load on our generous volunteers while elevating the signal to noise ratio of the forums otherwise arising from the same queries being posted repeatedly).
The Basics
- Nextcloud Server version (e.g., 29.x.x):
35.0.1
- Operating system and version (e.g., Ubuntu 24.04):
OpenMediaVault 8.5.10-1 (Debian 13)
- Web server and version (e.g, Apache 2.4.25):
2.4.68
- Reverse proxy and version _(e.g. nginx 1.27.2)
caddy 2.11.4
- PHP version (e.g, 8.3):
8.4.25
- Is this the first time you’ve seen this error? (Yes / No):
Yes
- When did this problem seem to first start?
I do not remember, but i would say around june/july
- Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
AIO (v14.2.0)
- Are you using CloudfIare, mod_security, or similar? (Yes / No)
Using a CF Domain, not CF tunnel, everything behind caddy
Summary of the issue you are facing:
After a few updates in the AiO UI, as usual Nextcloud would sometimes not update properly and I have to do manual maintenance, this is unrelated to the issue but it caused me to check the Overview tab in the Administration settings, which got me a few issues to fix, which I did, except for the Database Configuration. When I click on “Show the findings”, I get the following:
The snippet contains the following:
# postgresql.conf
shared_buffers = 256MB
Asking me to add it to the file mentioned above.
Since I’m using the AIO setup, I checked inside nextcloud-aio-database under /var/lib/postgresql/data/postgresql.conf which had shared_buffers set to 256MB. I’m a bit confused by this error, and also trying to edit that file will just reset it back to its original value of 256.
Steps to replicate it (hint: details matter!):

The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):
