Fonction save product

Bonjour,

j'utilise régulièrement la fonction save de la class product, et aujourd'hui elle me renvoie une erreur :
Error: Call to a member function get() on null: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'ORDER BY category_id DESC LIMIT 1)' at line 1

Voici le bout de code :

if(!@include_once(rtrim(JPATH_ADMINISTRATOR,DS).DS.'components'.DS.'com_hikashop'.DS.'helpers'.DS.'helper.php')){ return false; }
$productClass	= hikashop_get('class.product');
$Hconfig		= hikashop_config();

$product = new stdClass();

$db->setQuery('SELECT product_id FROM #__hikashop_product WHERE product_code = "'.trim($item['superproduct'].'"'));
$parent_id = $db->loadResult();
if(!empty($parent_id)){
	$product->product_parent_id		= $parent_id;
}
else{
	$product->product_parent_id		= 0;
}

$product->product_name				= trim($item['name_fr']);

if(empty($item['stocklevel']) OR $item['stocklevel'] == '-1'){ $product->product_quantity = 0; }
else{ $product->product_quantity	= $item['stocklevel']; }

$product->product_code				= $product_code;

$product->product_published	= intval($item['isavailable']);

if(trim($item['taxclass']) == 'none'){
	$product->product_tax_id		= 21;
}
elseif(trim($item['taxclass']) == 'normal'){
	$product->product_tax_id		= 19;
}
elseif(trim($item['taxclass']) == 'reduced'){
	$product->product_tax_id		= 20;
}
elseif(trim($item['taxclass']) == 'reduced2'){
	$product->product_tax_id		= 22;
}
elseif(trim($item['taxclass']) == 'superreduced'){
	$product->product_tax_id		= 23;
}

if($product->product_parent_id == 0){
	$product->product_type			= 'main';
}
else{
	$product->product_type			=  'variant';
}

$product->product_vendor_id			= 1;

$product->product_keywords			= trim($item['keywords_fr']);

$product->product_weight			= intval($item['weight']);
$product->product_weight_unit		= 'g';

$product->product_dimension_unit	= 'mm';
$product->product_width				= intval($item['width']);
$product->product_length			= intval($item['length']);
$product->product_height			= intval($item['height']);

$product->product_max_per_order		= 0;

$product->product_access			= 'all';

$product->product_group_after_purchase	= '';

$product->product_min_per_order		= intval($item['minorder']);

$product->product_page_title		= $product->product_name;

$product->product_alias				= JFilterOutput::stringURLSafe($product->product_name).'-'.$product_code;

$product->product_description		= $item['text_fr'];
$product->product_meta_description	= $item['text_fr'];

$price = new stdClass();
if(!empty($item['manufacturerprices_eur_net'])){
	$price->price_value				= str_replace(',', '.', $item['manufacturerprices_eur_net']);
}
else{
	$price->price_value				= str_replace(',', '.', $item['listprices_eur_net']);
}
$price->price_currency_id		= 1;
$price->price_min_quantity		= 0;
$product->prices				= array($price);

$product->categories	= array(2);

$product_id = $productClass->save($product);

Bonjour,

j'etais pourtant en mode debug au moment de lancer mon script, je n'ai aucune info de plus.

Je tiens à préciser que la ligne produit est quand même créée dans la table product (si ca peut donner un indice sur l'endroit de l'erreur)

EDIT :
J'ai désactivé le fichier error de mon template j'ai maintenant le classique carré rouge avec toutes les infos :

J'essaye d'avancer, l'erreur ne se produit pas si je suspend le déclenchement du triggerEvent onAfterProductCreate ligne 2792 de la class product

Je vais donc chercher parmi les multiples plugins que j'ai créé pour ce site interminable, ca vient surement de là, ne vous embêtez pas plus, désolée pour le dérangement.
