Hello,

No, it's not a blank page, it's a 404 because you have an issue whith your sef component.

So, what sef component do you using ?

it was a blank. but i have uninstal with error, trying to reinstal with error too
i come back when i see a litle more

the package i'm trying to install is kunena_1.5.9_SFK.zip

erroe i get is
Le fichier sélectionné n'a pas pu être copié.
JInstaller::install: Echec lors de la copie du fichier : /var/www/vhosts/jurdan.org/httpdocs/tmp/install_4b90f2fa5954d/admin.kunena.html.php vers /var/www/vhosts/jurdan.org/httpdocs/administrator/components/com_kunena/admin.kunena.html.php
