Error when uploading branding logo


  • Used Zammad version: 4.1.x
  • Used Zammad installation type: Package
  • Operating system: CENTOS
  • Browser + version: Edge or Chrome

Expected behavior:

  • To be able to upload a logo image for proper branding.

Actual behavior:

When Uploading PNG I get this error:

  • {“error”:“Permission denied @ rb_sysopen - /opt/zammad/public/assets/images/97be57ac80cd5343ce6627f75539d175.png”}

Steps to reproduce the behavior:

  • Try to upload images in my system.

Part of me believes it’s some odd permission issue with Ruby on Rails.

Ensure that all files and foldes within /opt/zammad/ belong to zammad:zammad.
You can double tab that by runnung chown -R zammad:zammad /opt/zammad/ which may take some time.

Also, as you mentioned CentOS, you may also want to double tab it’s not caused by SELinux:
