There is a strange error on my board; it seems that I'm not be able to delete a post attachment. I've double checked the settings didn't change a thing (It was working before)
Maybe one thing might have caused this; there was a problematic add-on that wasn't deleted properly and left a permission set in the permission group. I went to the developer section and deleted that.
I don't know how to troubleshoot this. How can we fix that?
Edit: The error I'm getting is "You do not have permission to view this page or perform this action. "
Edit 2: I've also tried my disabling the listeners via config, it still happens.
