First, I apologize for English.
I tried modifying the notifications of achievement, but I could not get it. And I would like notifications only show once. I searched the forum but either I'm stupid or I have not found the answer.
By default, notifications are to go on every page, so I would like this to change. Is it possible?
I found the filter "add_filter ('dpa_user_has_notifications', '__return_false')," but what it does is not display notifications.
Thanks for everything.
