Reply To: Portfolio error on more than 9 items and 404 error on next page

I had the same issue, but resolved it by allowing 40 profile options to show on one page. To do this, go to Appearance –> Editor –> Showcase Page Template and scroll down about half way and look for the code below:

$args=array(‘post_type’=> ‘portfolio’,'post_status’=> ‘publish’, ‘orderby’=> ‘menu_order’, ‘caller_get_posts’=>1, ‘paged’=>$paged, ‘posts_per_page’=>9);

Simply change the “‘posts_per_page’=>9″ to whatever number you want.
