Okay otto42, that did partially solve the problem… I used the query_posts() and put the 2.5 version of rewrite.php back and the code now works with permalinks set custom.

But now another problem has shown up, which involves multiple installs of WP.

I have two seperate blog installs at mydomain.com/blog1 and mydomain.com/blog2. Note that mydomain.com is outside all the WP installs.

An external program that tries to pull the posts out of each blog, always gets the blog1 posts, even when it should be getting blog2 posts. Here’s how to recreate:

Take the following code:

<?php
//Displays the title of the 3 most recent posts in the blog
require('./wp-blog-header.php');
query_posts('showposts=3');
if (have_posts()) : while (have_posts()) : the_post();
the_title();
?><br />
<?php endwhile; endif; ?>

Save it as BlogOnePosts.php and upload it to mydomain.com/blog1 directory. Now save the same code again as BlogTwoPosts.php and upload it to mydomain.com/blog2 directory.

Go to both mydomain.com/blog1/BlogOnePosts.php and then mydomain.com/blog2/BlogTwoPosts.php and you will see that they each correctly display the last three posts for each blog seperately.

Now take this code:

Blog 1<br />
<?php include('/home/public_html/blog1/BlogOnePosts.php'); ?>
<br /><br />
Blog 2<br />
<?php include('/home/public_html/blog2/BlogTwoPosts.php'); ?>

Save it as BlogPosts.php and upload it to your mydomain.com directory (outside both wordpress installs).

Now goto mydomain.com/BlogPosts.php

You will probably get an error message:
WARNING: require('./wp-blog-header') No Such File Or Directory
Not sure if this is expected behaviour, but here’s how we fix it…

In the BlogOnePosts.php change this line:
require('./wp-blog-header.php');
to this line:
require('/home/public_html/blog1/wp-blog-header.php');

Now in the BlogTwoPosts.php change this line:
require('./wp-blog-header.php');
to this line:
require('/home/public_html/blog2/wp-blog-header.php');

Now got back to mydomain.com/BlogPosts.php, and you see that Blog 1 shows the three most recent posts correctly, but Blog 2 shows the three most recent posts from Blog 1 as well instead of it’s own posts.

Fixed one problem… on to the next one!!!

Okay, I determined that the problem is somehow related to the includes/rewrite.php file.

The following short-term solution worked for me:

(1) Get a copy of rewrite.php from WP2.3.3 version here:
http://trac.wordpress.org/browser/branches/2.3/wp-includes/rewrite.php?format=raw

(2) Open it in a text editor, and comment out line 903 by putting two slashes (//) in front of it, so the line looks like this:
//generate_page_uri_index();

(3) In your current WP2.5 install, rename the includes/rewrite.php file to something like includes/rewrite.php.ORIG

(4) Upload the modified v2.3.3 rewrite.php file to the includes directory.

(5) Now go to the admin panel in WordPress and choose settings then permalinks. Change the setting back to default and hit save. Now choose your custom permalinks setting and hit save again.

If the problem is solved great!!!

If not, go delete the rewrite.php that you uploaded, rename the rewrite.php.ORIG back to rewrite.php, goto permalink settings and change it back to default and hit save.

Hope this helps somebody!!!

Scooby, I tested your code (had to add require(‘wp-blog-header.php’); at the top) and confirm that it does the same thing on my system… spits out Not Found!!!

Okay, just so I know I’m not crazy, try this piece of code:

<?php
require('wp-blog-header.php');
$myid=10; //put a post id here that you know is valid
$mytest = get_post($myid);
echo "Known good post id ".$myid." returns: ".$mytest->post_title;
$mytest = have_posts();
if ($mytest=="") { $mytest="nothing"; }
echo " and have_posts() returns: ".$mytest;
?>

If you stick a Post ID number in that you know is valid, it will correctly display the title, yet the have_posts() returns empty!

Any suggestions anybody?
