Yeah you're actually the second person to call me out on that. I don't always remember to do it because most of the time I never have do it. Oh well.
It's weird, but since they added the ability to view more than 20 posts per page, if you are still showing 20 per page, it includes the page number, which works fine for anyone still set to 20, but for anyone else, it is a challenge, like for example, it is hard to find page 1517, when you only see 759 pages.
Why they still haven't fixed that after all this time, I have no idea...
