Have you eventually played around with the theming of Nextcloud? The only location where I find a file called “server.css” on the server is the directory “./themes/example/core/css”.
I used an app “unsplash” (changing the background picture) in nextcloud 16, during the process to update to 17.0.1 the updater said its not compatible and it will be disabled. Which wasnt the case but nextcloud worked anyway. Out of a sudden nextcloud stopped working (the web login, the rest works) and I dont know why. I already disabled “unsplash” via console but this also didnt solve the issue.
Thanks for the suggestion. Unfortunately I am not that experienced, where should I put the file? And to add, I also find this file as “j-ed” mentioned in " ./themes/example/core/css"
I tried maintenance repair but that also did not help.
Digging into the log file I discovered, that (propably) every css ist not found and these error messages (below). And yes, all the files are present and I did not change them.
Can anyone help?
