Hello Par,
Yes you already record “_server_http_x_forwarded_for_0” entry at your database. But is there any option to make it show at default report page (without go to detail date/time)?
for me, I just sit patience meanwhile I disable it. When everything goes stable, I upgrade the plugin and enable it again. I can try to fix it, but this part is very critical and I am not confidence to fix it 🙂
