is there any detection message if the script fails to chmod?
marc

and add a detection in admin if the user forgets,

chmod is detected automatically in the installer scripts.

hello,
since commit 107, the installer dir www/setup is not deleted anymore. i've tested twice the install. previously it was deleted. after clicking on "visit the website", and log in, i'm back to install.

Additionnaly the line

"Remove the installation folder src from your server"
MUST be change to
"Remove the installation folder directory (www/setup) from your server"

improved description : ok fixed, thx
redirection issue : ok, fixed, thx
www/setup deletion : not fixed yet, it worked like a charm before, why is it not possible to keep it?

It requires write permission to delete folders/files, which is more complex and insecure.
