 * I want to turn on Database and Object Caching, but if I try to enable it
    W3 
   Total Cache asks me to manuelly copy the db.php and object-cache.php in wp-content:
 * > 3 Total Cache Error: Files and directories could not be automatically created
   > to complete the installation.
   > Please execute commands manually
   >  or use FTP form to allow W3 Total Cache make
   > it automatically. Execute next commands in a shell: cp /www/htdocs/w00d8912/
   > wp-content/plugins/w3-total-cache/wp-content/object-cache.php /www/htdocs/w00d8912/
   > wp-content/object-cache.php cp /www/htdocs/w00d8912/wp-content/plugins/w3-total-
   > cache/wp-content/db.php /www/htdocs/w00d8912/wp-content/db.php
 * I have done that and the db.php and object-cache.php is definitly in the wp-content
   folder, but nothing happens and the error message still occures. Also clearing
   the complete cache after copying the files doesn’t fix it.
 * What am I doing false? Or maybe is it a bug with WordPress 3.5.2?
 * Thanks in advance guys! This is the best caching plugin in the world! (Even when
   Database and Object Cache doesn’t function!)
