Hi @pvdm-github, do you have any customizations active?:

• Anything set in the "Custom HTML Head Content" customization setting?
• A APP_THEME env option set?

[pvdm-github]

Hi,

1. not that I'm aware of.
2. No.
   FYI it is a new default install with only a mediawiki import script run.

Okay, Can you share the output of running each of the following from your BookStack install directory on the command line:

• git status
• ls -alh themes
• ls -alh bootstrap/cache
