I am hosting my wordpress Website on an extern server. The people who are controlling it told me, that there is appearing a new message in the LogFiles constantly since some days:

AH00687: Negotiation: discovered file(s) matching request: /www/htdocs/asdf/yyy.com/index.html (None could be negotiated).

They also told me that they can do nothing to solve the problem since it does not appear on other websites they are hosting. Is there any idea how I could solve the problem? It seems to have negative impact on the videos that are played out via my ad network (I see that in declining figures in the ad network’s monitoring), but not on my clicks and views.
