For several days our notifications seem to be messed up. I got notifications that someone quoted me but a different user was quoted. Same with likes. It seems that every user gets every notification. Even notifications about likes of topics in closed categories. And its not possible to mark the notifications read.
There are some non official plugins installed. But I didn’t install any new plugin.
It seems that everyone gets the same notifications. Today I got a notification about a like for a posting of another user.
