your screen shot is accurate regarding the area I'm discussing.
However, in my case, it shows results (posts) 1 to 40 while the posts on the page are actually in the 600's....thus, it differs from the screen shot in that way. I consider the screen shot to be accurate. I consider what I see to be inaccurate (but certainly not a earth shattering issue)
I actually understand what it is talking about and am able to ignore the incorrect information and have been doing so for some time...just thought I'd mention it.
That's odd because I'm also using Firefox, but on my computer the results are accurate. In this case it says "Results 661 to 670 of 670" as I'm typing this reply. Have you tried clearing your cache?
