problemi di paginazione

http://spazifluidi.altervista.org/blog/?page_id=51

Ho modificato dei file del tema slim ma nonostante il codice sia presumo corretto non mi compare la paginazione: qualcuno sa dove possa essere il problema? vi allego il file index.php,il file (blog.php) del template che include
e il file della pagination.php (che è quello originale, che non ho modificato).

Con le impostazioni di defaul (cioè con articoli in home) la paginazione funziona, ma se cambio le impostazione di wordpress con pagina articoli diversa da home creava problemi...
grazie

<div id="feat-posts">
<?php query_posts(array(
'category_name' => ' '. $featcat .' ',
