I´ve tried to install WP Super Cache in my new dedicated server, however it doesn´t work. The installation was fine but WP Super Cache creates a folder named "blogs" instead "supercache" inside "cache" folder.
I changed the name to "supercache" but the plugin turns to create "blogs" again. I also make some tests by uploading some archives of old supercache installation and the WP Super Cache reconigzed these files in the "fake" "cache/supercache/'my site name'/" folder.
But, obviously, the plugin doesn´t create no one real cached page until now.
