PHP version: 8.1.11
The issue you are facing:
Hello,
After upgrading NextCloud from version 24 to 25, I can no longer see my files from the web interface with an error message: this directory is unavailable. The client (appImage 3.6.1) does not synchronize anymore and tells me: error while reading directory "".
I suspect a problem with the 32bit version of my system but unfortunately I don’t have the opportunity to reinstall my system in 64bit for a while.
If anyone has an idea… thanks in advance 
Is this the first time you’ve seen this error?: Yes
Steps to replicate it:
- Update NC from 24 to 25
- Login to WebUI
- Go to Files
- See error: “ce répertoire est indisponible” (“this directory is unavailable”)
