Sorry, you need to enable sending referrers, for this feature to work.
Huh? I get this when trying to delete a post. I know it’s something with my firewall(s), but why should sending headers be required?? It seems kinda strange to absolutely require that when a lot of people are going to be denied access for that reason.
Is there any way around this? Because if there isn’t, I either have to configure a software firewall and two hardware firewalls to permit WordPress to work, or just switch to something else!
