documents folder made invisible by turning off iCloud as default for saving

Hello all,

My save dialog kept showing a folder that does not exist, so based on a suggestion in the thread linked below, I used the following command in the terminal:

defaults write NSGlobalDomain NSDocumentSaveNewDocumentsToCloud -bool false

After this, the system settings showed that iCloud is full although I have never knowingly used it and just before it had been green.

But more disturbingly, my documents folder was made invisible.

I tried to reverse the command by

defaults write NSGlobalDomain NSDocumentSaveNewDocumentsToCloud -bool false

but that didn't do anything.

I can normally access the documents for now, but I find this very disturbing. If anyone could explain to me, what happened and how to fix it I would greatly appreciate it.

This is the thread where the terminal command came from:
