I was hit by spammer and got 100 notifications that are left after deleting his account, how can I removethem in bulk?
You delete the account in the wrong way. Please follow this doc to see the right way to delete the user account with all wpForo content: https://wpforo.com/docs/root/members/member-manager/
In any case, to delete the notifications, you need to go to the Dashboard > Forums > Moderation tab, check the topics you want to delete, and delete them using the Bulk actions > delete option.
I've deleted him using the same method as in your post. The notifications I'm stuck with are for "new reply" from his posts, the posts that are now gone.
I think an option to mark all notifications as read is a good idea.
How to remove them now, the option you described isn't for me since I don't have any more spam content.
Nvm I just noticed that you have clear all button. On my website the color is the same as the background and I didn't see it lol.
Thanks for your help.
