[Plugin: WP-Paginate] Page navigation not showing up

Hi
I just installed WP-Paginate and I don’t see that page navigation is showing up. I also can’t get WP Navi to work so I suspect it’s something I have set incorrectly on my end. I do have a child theme functions file (using Graphene) where I’m using Ambrosite previous/next plug in for post navigation. Perhaps it’s conflicting?

The code I’m using for that is
add_filter( ‘graphene_slider_post_type’, ‘graphene_slider_post_types’ );
// attaches the function my_post_nav to the hook graphene_post_nav
add_action (‘graphene_after_post_content’, ‘my_post_nav’);
// our function

function my_post_nav(){
// this will allow us to use other hooks but still only show on single posts
if ( is_single() && ! is_page() ) : ?>
<div id=”my-post-nav”> <!– div to contain your links –>
<?php previous_post_link_plus( array(
‘order_by’ => ‘menu_order’,
‘loop’ => false,
‘max_length’ => 0,
‘tooltip’ => ‘Previous page’,
‘in_same_cat’ => true,
‘ex_cats’ => ’12’
) );?> |
<?php next_post_link_plus( array(
‘order_by’ => ‘menu_order’,
‘loop’ => false,
‘max_length’ => 0,
‘tooltip’ => ‘Next page’,
‘in_same_cat’ => true,
‘ex_cats’ => ’12’
) );?>
</div>
<?php endif;

Would this make it so other paging systems don’t work?
Is there a way to use it with a hook in my functions file?

Thanks in advance for any help.
