I've been on this problem for a week now. I've searched through countless posts that just aren't answering the question. It seems that my wp_query breaks pagination. I've looked through a lot of the post on wp_query and pagination on here but with still no joy.

As far as I can see it's set up correctly. I have one instance where it will show all posts in one page, and in the other it repeats the content on each page. See the code below for a stripped down version with notes.

Can anyone see what the problem is?

<?php 
/* 

    Let's asume that this is the search query in the address bar: 
    ?s=media&trend=&industry=&d=2012-05-17|2012-11-17
    (To iterate, it's saying search for keyword 'media' 
    posted between 17th May 2012 and 17th Novemer 2012)

    It gives 13 results and shows all on the same page. 
    I have set show 10 posts per page so it should be cutting off 
    at first 10. 

    PAGINATION: On line 56 If I change the code to 
    $wp_query->max_num_pages, the pagination works but then 
    repeats the same 10 posts.

• 1 showposts and posts_per_page are conflicting. They do the same thing, and the former is deprecated, but you have them set differently. I don't know it that is the problem or not, but it is something I noticed. – s_ha_dum Commented Nov 17, 2012 at 15:42
• Iv'e corrected this. And thanks but no joy. Any other ideas? – zilj Commented Nov 17, 2012 at 15:50
• what does the URL look like for the second page? have you inspected the value of the paged query var to be sure it's what you expect? also print_r($allsearch) to see the SQL that WordPress is generating. – Milo Commented Nov 17, 2012 at 16:30
• I checked all of that, but i managed to almost get it working by adding in $limit = get_option('posts_per_page'); and posts_per_page=".$limit.". This works but now my $wp_query->post_count shows '10' on every page, even if 13 results are found. Almost there!! – zilj Commented Nov 17, 2012 at 16:34
• 4 $wp_query->post_count is referring to a different query. part of the issue is that you're using pagination parameters from the main query, but then creating an entirely new query. try using pre_get_posts to manipulate the query instead, it doesn't waste a query and will make these pagination issues go away. – Milo Commented Nov 17, 2012 at 17:37

If you want to stay with a new Wp Query, as in your example, changing your $allsearch name for the query variable to $wp_query should do the trick. Looks like the pagination functions are expecting that variable name for the query... So, try that...
