I have installed the W3 Total cache but It is showing error and errors are "(1) FTP credentials don't allow to copy to file /u2/www/00authors/wp-content/advanced-cache.php" "(2) W3 Total Cache Error: Files and directories could not be automatically created to complete the installation."
So How do i solve these?
You'll need to FTP in to your server and manually create the advanced-cache.php document. The content for the file can be found here:
