Not working with theme

Hi, I just downloaded your plugin, thanks for creating it. I activated it and changed the shop columns. I nedd them to be 4 (or at least 3) but my products keep showing up in a weird 2/1 column layout. I Think there must be a conflict with the theme I′m using.

Here′s the related code on the theme content.php file, if you could have a look I′d really appreciate any suggestions, thanks!

// Change number of products per page
add_filter(‘loop_shop_per_page’, ‘tpath_woo_loop_shop_per_page’);

function tpath_woo_loop_shop_per_page() {
global $tpath_options;

parse_str($_SERVER[‘QUERY_STRING’], $params);

if( isset( $tpath_options[‘tpath_loop_products_per_page’] ) && $tpath_options[‘tpath_loop_products_per_page’] != ” ) {
$products_per_page = $tpath_options[‘tpath_loop_products_per_page’];
} else {
$products_per_page = 12;
}

$product_count = !empty($params[‘product_count’]) ? $params[‘product_count’] : $products_per_page;

return $product_count;
}

// Change number of products per row to 4
add_filter(‘loop_shop_columns’, ‘tpath_woo_loop_columns’);

function tpath_woo_loop_columns() {

global $tpath_options;

if( isset( $tpath_options[‘tpath_loop_shop_columns’] ) && $tpath_options[‘tpath_loop_shop_columns’] != ” ) {
$product_columns = $tpath_options[‘tpath_loop_shop_columns’];
} else {
$product_columns = 3;
}

return $product_columns;
}

// Related Products Count
remove_action( ‘woocommerce_after_single_product_summary’, ‘woocommerce_output_related_products’, 20 );
add_action(‘woocommerce_after_single_product_summary’, ‘tpath_woocommerce_output_related_products’, 15);

function tpath_woocommerce_output_related_products() {
global $tpath_options;

if( isset( $tpath_options[‘tpath_related_products_count’] ) && $tpath_options[‘tpath_related_products_count’] != ” ) {
$related_count = $tpath_options[‘tpath_related_products_count’];
} else {
$related_count = 3;
}

$args = array(
‘posts_per_page’ => $related_count,
‘columns’ => $related_count,
‘orderby’ => ‘rand’
);

woocommerce_related_products( apply_filters( ‘woocommerce_output_related_products_args’, $args ) );
}
