it is in ‘navigation.php’
you probably need to edit this bit:
<?php } else { ?>
<?php /* global $pagenow; echo $pagenow; */ $redo_asidescategory = get_option('redo_asidescategory');?>
<div class="navigation <?php if ( is_home() and $redo_asidescategory != 0 ) { echo 'rightmargin'; } ?>">
<?php $_SERVER['REQUEST_URI'] = preg_replace("/(.*?).php(.*?)&(.*?)&(.*?)&_=/","$2$3",$_SERVER['REQUEST_URI']); ?>
<div class="left"><?php next_posts_link('<span>«</span> '.__('Previous Entries','redo_domain').''); ?></div>
<div class="right"><?php previous_posts_link(''.__('Next Entries','redo_domain').' <span>»</span>'); ?></div>
<div class="clear"></div>
</div>
<?php } ?>
and include the link to your plugin:
<?php } else { ?>
<?php /* global $pagenow; echo $pagenow; */ $redo_asidescategory = get_option('redo_asidescategory');?>
<div class="navigation <?php if ( is_home() and $redo_asidescategory != 0 ) { echo 'rightmargin'; } ?>">
<?php $_SERVER['REQUEST_URI'] = preg_replace("/(.*?).php(.*?)&(.*?)&(.*?)&_=/","$2$3",$_SERVER['REQUEST_URI']); ?>
<?php if(function_exists('wp_pagenavi')) wp_pagenavi(); else { ?>
<div class="left"><?php next_posts_link('<span>«</span> '.__('Previous Entries','redo_domain').''); ?></div>
<div class="right"><?php previous_posts_link(''.__('Next Entries','redo_domain').' <span>»</span>'); ?></div>
<?php endif; ?>
<div class="clear"></div>
</div>
<?php } ?>
hope you can figure out what to change where, and hope this works, good luck ??
