由于似乎没有任何效果，我决定检查数据库.

As nothing seemed to work, I decided to inspect the database.

将表users中的字段user_local从0更改为1可以解决问题.我无法想象这是SonarQube推荐的，但是到目前为止，我还没有发现任何副作用.

Changing field user_local in table users from 0 to 1 did the trick. I can't imagine this being recommended by SonarQube, but as of now, I did not find any side effects.
