Yes the error is because that contact has been either unsubscribed, set to “do not contact”, or their email is bouncing.
The challenge is that these notifications are hundreds, and they are using the same window that mautic uses to notify a new update. Hopefully I don’t miss it!
The reason for the notifications doesn’t matter. The problem is that they keep coming back. I clear all, when the page is refreshed, they come right back.
Same issue here. A very long list of notifications for a solved campaign issue of 26d ago keep still re-appearing. Desperately hoping for an update and solution to clear all.
It’s been a while, but in case anyone finds this, I suspect this is/was only happening to people who are running very old versions of mautic - it was happening to me back near the beginning of v3.
Sadly, if you’ve upgraded to a newer version (I’m currently running 4.5), those notifications still persist when you clear all. I’ve been ignoring them for a long time.
Anyway, I dont know what caused it, but if you want to fix it, you can go into the database and clear out the “notifications” table. Haven’t had a problem since.
