not sure we're on the same page, so to clarify. i meant my own ads added via ad manager.
to this day they popped up without a problem, but today they are gone, although when i look at the page source of the embedded video page my script is there. not sure why they don't show up, thats why i asked if you disabled/blocked it or something. i tested my ad script elsewhere and it works fine.
as to your ads popping like crazy even with 0% profit admode, yes I experienced it all the time, but surprisingly, today it work as it should only one ad pops up.
