Blank ad spaces in forum threads
Webmasters,When I logged in just now (8.40p.m.), I could see grey squares next to the box where we post a forum response in most of the forum threads. There is no ad at all in it, though I could see the small arrow to indicate it is a Google AdSense ad unit display. In a few threads, I also saw this blank grey square just below the heading of "Create a poll for this forum thread" - there should be 2 ads there, but I could see only one, with the one on the right side being blank.
I cannot provide screen shots as there seems to be some problem with my PC for this tool.
