How would you get three loops to work. Basically, in this order: Feature loop (1 post), Standard Loop (1 posts), Specific Category Loop (5 posts). I'm trying not to repeat content between the three loops. I have the Feature Loop and Standard loop working, I'm just not getting the third (Specific Category) loop to function. Thanks.

I had incorrectly placed the code to remove the filter. Now that I have corrected that the problem is slightly different. When I click the "Previous Post" link, it still displays the error, and the chronologically lists the 5 last posts (not 6-10, but 1-5 from the first page). No "Previous Posts" link appears at the bottom of this 2nd page. In effect, it displays the first page all over again without the exclusions and then fails to display the navigation. Just to clarify.

I have come across a new problem however. When I click the "Previous Posts" link, it displays an error (see below) and then proceeds to display all my posts, including those already displayed. If I keep clicking "Previous Posts" it will even display posts not yet published, but in Draft mode, and also all my pages (Contact, About). The error I get: Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'post_strip' was given in /../wp-includes/plugin.php on line 163 I am using WordPress 2.5 Also, my setup is a little different than your example loop. I display the last article from one author in one loop and save the ID. Then I have another loop that displays the last post from the other author, and it makes the variable = variable + new ID. Then I run the generic loop to display the last 5 posts excluding the two that have already been displayed. This is to feature the last post from each author at the top. Just slightly different from your example. It works fine except for the navigation. TIA for any help. Thank you so much Ronald for this post - it has helped me greatly.

If there are two duplicates, then only three would be shown. @Johnbillion, You hit the nail on the head. That's why I decided to modify the original query, which would return the correct number of posts without the duplicates. @All, As Epic pointed out, posting code here is problematic.

Your code is removing the duplicate posts after five have been selected from the database. If two of those are duplicates, only the remaining three will be shown. If all five are duplicates, no posts will be shown! Do correct me if I'm wrong as I haven't tested your code. @Epic Alex

Basically I think there is a quicker and easier way of doing this, by storing the ids in an array and then searching that array in the second loop.
