I have installed a new blog in "network" configuration (ex MU) with "multi-path" option (no multidomain), and I have activated the w3tc (0.9.2.3) plug-in on the root blog.
I have followed the instructions in the admin page of the plug-in and I've adopted the "auto-install" bottons to update my (root) .htaccess. My web server is Apache httpd 2.2.19 with mod_rewrite active, PHP 5.3.6 and all other packages referenced in the "install" section of w3tc admin page.
The problem is that ALL pages excluded the homepage of root blog return a 404 error.
The problem disappear when i change in .htaccess the line:
RewriteBase /home/a427137/deploy/wordpress_beta/ (the physical path of wordpress installation)
RewriteBase /wpbeta/ (the URI of root blog)
But at this point the w3tc admin page marks an error in .htaccess!
Any idea to resolve my problem
Thanks a lot
