I just installed WP on LAMP, using http://codex.wordpress.org/Giving_WordPress_Its_Own_Directory :
/var/www/index.php (WP index.php)
/var/www/wordpress (all the WP files except index.php)
After that I wanted to secure my setup defining my Apache virtual host this way :
Deny for all
allow from all
Allow from all
But it doesn't work :
Forbidden You don't have permission to access / on this server.
If I replace index.php with any index.html, it does work....
Any idea ?
