- Is this the first time you’ve seen this error? (Yes / No):
- No - Got this since months, but had no time to search for a fix for that problem
- When did this problem seem to first start?
- Don´t know. Could be weeks or months
- Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
- Docker Compose (Portainer)
- Are you using CloudfIare, mod_security, or similar? (Yes / No)
- Yes, I am using Cloudflare for my domain (

- Yes, I am using Cloudflare for my domain (
Summary of the issue you are facing:
I recently set up Nextcloud via Docker Compose. The container is accessible locally (via IP:Port) and externally via my domain through Nginx Proxy Manager and Cloudflare.
However, when I log into the WebUI and click on the 9-dot app menu in the top right corner to open certain apps, I only get a completely blank/white page.
This issue occurs with the following apps:
-
Files
-
Activity
-
Mail
-
Photos
-
Notes
Other parts of Nextcloud (like the Dashboard, Administration settings, etc.) work perfectly fine. The behavior is identical whether I access Nextcloud locally via my NAS IP (192.168.178.123) or externally through the reverse proxy.
Steps to replicate it (hint: details matter!):
-
Log in to the Nextcloud WebUI.
-
Click on the 9-dot app menu in the top right corner.
-
Select an affected app (e.g., Photos or Files).
-
The page loads completely blank.
Log entries
Nextcloud
Please provide the log entries from your Nextcloud log that are generated during the time of problem (via the Copy raw option from Administration settings->Logging screen or from your nextcloud.log located in your data directory). Feel free to use a pastebin/gist service if necessary.
Log was too big for pastebin, so I share it with my Google Drive

Web Browser
If the problem is related to the Web interface, open your browser inspector Console and Network tabs while refreshing (reloading) and reproducing the problem. Provide any relevant output/errors here that appear.

Turns out it was a mix of a few configuration hiccups, but there was one main culprit causing the white screen. Here is exactly what I did to fix my setup, in case anyone else runs into this:
