  • Hello,

    I have noticed that when I specify a search query with posts_per_page equal to X, when the setting for “blog pages show at most” is Y, if X is less than Y, WordPress will show some 404s.

    Here is an example to make it clearer:

    Let’s say under my admin settings, I set “Blog pages show at most” to 12. In search.php, I put:

    <?php $posts=query_posts($query_string . '&posts_per_page=7'); ?>

    Let’s say a user searches for a term with 26 posts as a result. If I had not put my custom posts_per_page in search.php, the result would show in 3 pages:

    first page: results 1 – 12
    second page: results 13 – 24
    third page: results 25 – 26

    But since I specified posts_per_page as 7, it should show 4 pages of results:

    first page: results 1 – 7
    second page: results 8 – 14
    third page: results 15 – 21
    fourth page: 22 – 26

    The first three pages load fine, but then when I click “next page” for the fourth page, WordPress still thinks that there are only three pages to show, so it will give a 404 on the last page.

    This can be easily fixed by making sure that the value for posts_per_page is greater than or equal to the number for “blog pages show at most”. But I think it should work in both cases. 🙂
