Hallo,
get the message:„Downgrading is not supported and is likely to cause unpredictable issues (from 27.0.0.8 to 26.0.4.2)“
Nextcloud version: 27.0.0
Operating system and version : openSUSE Tumbleweed VERSION="20230623"
Apache or nginx version: Apache 2.4.57
PHP version: 8.2.7
The issue you are facing: Downgrading is not supported and is likely to cause unpredictable issues (from 27.0.0.8 to 26.0.4.2) although I didn’t initiate it and didn’t want it.
Is this the first time you’ve seen this error? (Y/N): N
Steps to replicate it:
- I have no idea how to find the cause.
