How you see, only 8 ads are visible in page but I have 14 ads. I have read about ad limitations here but can't understand is it my situation or not ? Can someone give me exact answer why I can't see more than 8 ads ? Can it be some premium account for seeing more ads ?
Link stated on the page you refer:
Ad limit per page
Currently, on each page AdSense publishers may place:
Up to three AdSense for content units
Up to three link units
Up to two search boxes
You are trying to put more than three content units on one page.
