Solved: Chrome does not store passwords anymore

For some reason my Chrome did not autofill stored passwords anymore.
The list of stored passwords was empty and even when I saved a new password, the next time it would not be autofilled.

Problem: maybe the local database broke.

Solution: Force to reload the list from the Cloud by removing the local database.

Under Linux that is:

cd ~/.config/google-chrome/Default
mv ./Login\ Data-journal ./Login\ Data-journal.bak
mv ./Login\ Data ./Login\ Data.bak
