For some reason, I can only see 61 posts per page in a thread. I can tell that most threads have 100 posts per page, because I can always go to page 2 of a thread and it starts with 101. So basically I miss the last 40 posts of any thread. If a thread has 3 pages, I can see 1-61 of page one and 101-160 (or so) of page two, etc. I'm missing so many posts that I feel I can't post anything because I assume my question or comment has already been added, but I can't tell for sure.
Do I have some setting configured wrong? I've never messed with any settings here, so I assume they are set to a default.
