Override Tools.php + rewriting

itklif · December 4, 2012

Bonjour,

j'ai un soucis en essayant de faire un override de Tools.php ...

même en gardant le même contenu que classes/Tools.php (cf ci dessous) et en l'enregistrant dans override/classes/Tools.php j'ai un problème d'accès à mon site

>> le rewriting ne se fait plus

impossible d'accéder à www.monsite.fr ->>> page blanche

mais www.monsite.fr/fr/ fonctionne ...

une idée ? je suis en 1.4.8.3

merci de votre aide, je rame ....
