Free extensions for Joomla!

Hi,

Since updating to PHP 5.4, I've encountered the following error with WP Posts:

Warning: Creating default object from empty value in /homepages/45/d352879194/htdocs/modules/mod_wpposts/helper.php on line 88

Warning: Creating default object from empty value in /homepages/45/d352879194/htdocs/modules/mod_wpposts/helper.php on line 88

Here is the code from line 85 - 93:

foreach ( $rows as $row )
{
if ($row->post_type == 'post') {
$lists[$i]->link = $wpBaseUrl.'/?p='.$row->ID;
} else {
$lists[$i]->link = $wpBaseUrl.'/?page_id='.$row->ID;
}
$lists[$i]->title = htmlspecialchars( $row->post_title );
$lists[$i]->readmore = false;

Experienced no problems with WP Posts since the PHP update.
