when i click on "new posts" and then on "Recent Posts"
i get 10 pages of posts,
then i click 0n page 10. but i hove no more option to see more old posts.
only this message: Showing results 181 to 198 of 198. that is it.
but i need to see older posts (for example posts number 10000-10100 from 995393)
This is also limited by the "Read Marking Data Lifetime (Days)" option, which defaults to 30 days. You can increase it, but I wouldn't go too high as there are performance implications (it's limited to a year).
