Ok so it works on your site
So does this mean, I have to install the last booklibrary version for it to work?

This is what sows in the booklibrary.html.php code


<?php
if(strpos($currentcat->header,_BOOKLIBRARY_LABEL_SEARCH) && count($rows) == 0 ){
?>
<div class="componentheading<?php echo $params->get( 'pageclass_sfx' ); ?>">
<?php echo _BOOKLIBRARY_NOTHING_FOUND; ?>
</div>
<?php
return;
}

if($params->get('show_search'){
?>

and ... ???
