"Add the code where you find previous_post () and next_post () functions. If you can not find these tags, place the code Between endwhile, and endif, in the_loop.

Code to add in your theme
<? php if (function_exists ('wp_page_numbers')): wp_page_numbers (); endif;?> "

but I can not find the template of where I wtawić this code?
