Hi enoch85,
I read it. Without - hoppefully, from security view descript in nextcloud forum - because phpinfo() says other - imagemagick php module was gone.
The warning goes away with occ app:disable theming , descript as behind your hyperlink.
From my point, i like imagemagick. The server runs only in local network enviroment, and only known users have the permission to write. This gives me a good overview about security, I think. And so I think I have more negativ effects without imagemagick.
Hopefully the developer find a good solution to that.
Thank you, and bye!
