après migration vers serveur OVH search mobule erreur

fly_in_the_sky · November 6, 2014

Bonjour,

Je viens de migré un prestashop 1.3.2 ,de gandi à ovh. Et mon bloque recherche renvoie une erreur :

Warning: preg_replace(): Compilation failed: disallowed Unicode code point (>= 0xd800 && <= 0xdfff) at offset 1816 in /home/cassenoihl/www/casse-noisettes/shop/classes/Search.php on line 98

voici la ligne 98 :

$string = preg_replace('/['.PREG_CLASS_SEARCH_EXCLUDE.']+/u', ' ', $string);

J'ai éssayer de modifié comme j'ai vu sur d'autre topic , la ligne

‘\x{a806}\x{a80b}\x{a823}-\x{a82b}\x{d800}-\x{f8ff}\x{fb1e}\x{fb29}\x{fd3e}’ in the line 43 with "e800"

Il n'y a plus d'erreur, mais par contre, le module ne renoie pas de résultat... donc cela ne fonctionne toujours pas..

Voici mon fichier search.php original :

Merci pour votre aide.
