I’m experiencing the same issue and have implemented near on all code examples and modified versions of them with no luck.

I’ve posted the details on this post

Additional to this is the $wp_query which is in blog.php that may help identify the issue rather than adding code to functions.php.

$numwords = 100;

$temp = $wp_query;
$wp_query= null;
$wp_query = new WP_Query();
$wp_query->query('post_type=post&showposts=5'.'&paged='.$paged);

$ct=0;

while ($wp_query->have_posts()) : $wp_query->the_post();

$ct++;
	if($ct%2==1)
		$bg="DAD5D5";
	else
		$bg="FFFFFF";
	$strippedDesc = strip_tags(get_the_content());
	preg_match("/([\S]+\s*){0,$numwords}/", $strippedDesc, $regs);
	$shortDesc = trim($regs[0])." [...]";
		if(trim($regs[0])=="")
	{
		$shortDesc = substr($strippedDesc,0,600)." [...]";
	}

Forgot to add that I thought it was just a /page/2/ issue but it turns out it’s the last page that causes the issue.

There are a few categories that stop at /page/3/ and cause the 404 as well as another that gets to something like /page/9/ before it produces a 404. (These show up on Google Webmaster Tools

An infinite loop problem but I’ve struggled to pinpoint the root cause.

For reference, this is the blog URL

keesiemeijer,

I’ve had some success with the code but it has moved the issue slightly (and thanks for the code by the way!)

Original Symptoms as follow
1. Each Category archive would show the first page
2. Moving to /page/2/ on each Categories and it would produce a 404.

Originally I thought it was a WordPress issue since the website was upgraded to WordPress 3.4 but after extensive analysis, it appears to be the theme.

Implementing the Code
It helped in terms of getting past the issue of a 404 on /page/2/ (and thought it had cracked it to be honest) but the site now gets a 404 on any category URL that pass /page/3/

That is, /page/3/ is working but going to the “previous Page” or “Older Entries” produces a 404 on /page/4/

This is the code that has helped the most

function my_post_queries( $query ) {
  if (!is_admin() && $query->is_main_query()){
    if(is_home() || is_category() || is_tag() || is_search() ){
		$query->set('posts_per_page', 1);
    }
  }
}
add_action( 'pre_get_posts', 'my_post_queries' );

Any advise on the code would be a great help as I have tried near on everything in the WordPress Forum on this issue and various combinations thereof.

There are no plugins that play with the URL and I’ve also noticed that this applies to TAGS as well as CATEGORIES.

This is an example of a category that produced a 404 if you click on the “Older Entries” link and go beyond /page3/

Many Thanks and hope you’re able to assist.
