Bonjour,

        j'ai un site de dépose d'annonces en cours de construction et depuis peu quand les personnes inscritent sur le site veulent déposer une annonce après avoir remplis les champs styles : objet, prix, département..... et le souci arrive quand les gens valident l'annonce pour la mise en ligne... un page online apparait (mon hébergeur) avec une erreur 500 pour cause de problème redirection htaccess ou de code...

        Comment faire pour solutionner le problème car je cale depuis plusieurs jours... ?

Merci par avance.

vous trouverez ci-dessous mon fichier htaccess :
