I just uninstalled WP Super Cache and installed W3 Super Cache. However, I am getting this message at top of every page in back-end:
Page caching is not available: advanced-cache.php is not installed. Either the /home/******/public_html/wp-content directory is not write-able or you have another caching plugin installed. This error message will automatically disappear once the change is successfully made.
Can you tell where I can get advanced-cache.php ?
