I have a new TP-LINK router and I noticed that not all options are accessible using Opera. The System Logs and Statistics don't work. This is happening both with Opera Stable and Opera Developer.
Both Google Chrome and Mozilla Firefox can access all options. On TP-LINK support, it was told me the problem was the navigator (Opera).
OS: Xubuntu 17.04 amd64
Window manager: xfwm4
Opera Stable version: 46.0.2597.32
Opera Developer version: 48.0.2636.0

Deactivating ad blocker have solved it.
But this is strange. Why does this happen?
