 * I tried to install ZenCache.
    I get “Failed to update your /wp-content/advanced-
   cache.php file. …”.
 * I created “advanced-cache.php” file and chmod this file to 666.
    Still the same
   error. What is wrong?

 * Sorry, it was typo mistake and I didn’t set right permissions.
 * But now I still have problem – after I press Save All Changes, it opens blank
   page. In URL I can find [http://www.xxxxxx.yy/wp-admin/admin.php?page=zencache&_wpnonce=a444d4100e](http://www.xxxxxx.yy/wp-admin/admin.php?page=zencache&_wpnonce=a444d4100e)
 * And I can’t find anything about Zencache in View Source after reloading website(
   in other browser, without being logged).
 * Any idea?
