 * Hi,
 * Can anyone help me? After activating the plugin the whole site fell down getting
   en error 500, even the admin panel.
 * If I comment the following line at wp-config.php which was created by the plugin
   activation:
 * //define( ‘WPCACHEHOME’, ‘/var/www/path-to/wp-super-cache/’ ); //Added by WP-
   Cache Manager
 * then the the site works again but without the plugin working correctly (of course).
 * If I go to the error_log there is nothing. Can anybody help me please?
 * Thanks,

 * Hi, I found the solution. I write down this for people who have the same problem,
   and maybe I could help them.
 * The problem was at the APC cache of PHP. If you disable this by adding at .htaccess
   the following directive then the website works again:
 * php_flag apc.cache_by_default Off
 * Regards,
