Hi, Justin.
Thanks for your response.
I am pretty sure that i did not installed any new theme and the theme I have been using for two years (Division) do not include those options.
However, I tried deleting the themes and plugins folders. Those options were still there. After restoring from a former backup, they are still there.
My only action before those options appeared was to review some e commerce plugins.
As I said, is quite annoying.
Thanks anyway.
