I don't know what else to check, I reinstalled wp-super-cache 0.9.7 following every line of the instrucions, activated by the admin page but nothing gets actually cached.
- I double checked .htaccess files in both document root and cache directory
- All directory permissions are granted to the webserver user
- WP_CACHE constant is defined to true
- PHP safe mode is disabled
What else can I do to finally get this plugin working?
