WordPress plugin pagenavi, I can't see more then 2 pages, even with 100+ posts

That's how it's looks with 20 posts, and only four posts shows.

With this, I have 20 posts in this category, I'm showing on the single page only four of them, so i should get 5 pages of navi page plagin, but I get only two of them, and it's doesn't metter how many posts I have.

尝试像这样更新 wp_pagenavi 使用：

<?php if (function_exists('wp_pagenavi')) wp_pagenavi( array( 'query' => $myposts ) ); ?>
