 * Me too.
 * I fixed it by deleting the advanced-cache.php file in /wp-content/.

 * already removed the plugin according to this:
    [http://zencache.com/kb-article/how-do-i-uninstall-zencache/#toc-86754ab8](http://zencache.com/kb-article/how-do-i-uninstall-zencache/#toc-86754ab8)
 * the point is that the website runs on networking and the reason changed to zencache
   was that other cache plugins does not support (well) such weibites, but I am 
   afraid that zencache has also problems to manage such sites.

 * the advanced-cache.php file didn’t update. As tarpey mentioned, delete it to 
   fetch it again.

 * I’ve already removed it completely according to instructions given by the author.
   Now the site runs without any cache plugin.
    I’ll wait for the next update of
   zencache in order to avoid further desasters.
 * thanks for response also to [@tarpey](https://wordpress.org/support/users/tarpey/)!

   I have confirmed that this is a bug in the latest release and I’ve posted a temporary
   workaround here: [https://github.com/websharks/zencache/issues/524#issuecomment-120565866](https://github.com/websharks/zencache/issues/524#issuecomment-120565866)
 * This will be fixed in the next update.

 * I just wanted to leave an update on this bug for everyone who experienced this
   issue: This issue only occurs if your site happens to have `WP_DEBUG` enabled
   when you update ZenCache from v150629 → v150709. When debugging is enabled during
   the upgrade from v150629 to the latest version, the fatal error occurs and then,
   because of that fatal error, ZenCache is not able to update `advanced-cache.php`.
 * However, when `WP_DEBUG` is disabled, the fatal error does not occur and immediately
   after the plugin update ZenCache is able to automatically update the `advanced-
   cache.php` file. Once ZenCache updates the `advanced-cache.php` file, the issue
   that’s causing the fatal error when `WP_DEBUG` is enabled is fixed.
 * The temporary workaround that I posted [here](https://github.com/websharks/zencache/issues/524#issuecomment-120565866)
   will work for everyone who has already been affected by this fatal error, however
   I will be releasing an update this week that includes a patch for this problem
   so that even if you’re upgrading from v150629 to the latest version with `WP_DEBUG`
   enabled, you won’t experience the fatal error. If you haven’t updated from v150629
   to v150709 yet and you do have `WP_DEBUG` enabled, then you can safely update
   by simply setting `define(WP_DEBUG, false);` in your `wp-config.php` file, running
   the update, and then re-enabling `WP_DEBUG. Or you can simply wait until the 
   next release later this week. 🙂

    thanks for sharing 
   the workaround, nonetheless I’d rather wait until the update is published 😉
 * it would be very helpful if you would announce the update here in a brief note.

   [@massimod](https://wordpress.org/support/users/massimod/) This has been fixed
   in the latest release (v150718, released today). Upgrades from v150629 to the
   latest version will work fine now even with `WP_DEBUG` enabled.

 * Yes, you should have no issue doing that.

 * BTW…I do not have WP_Debug enabled and the problematic update, and it’s correction,
   created a fatal error preventing admin access. (Fatal error: Call to a member
   function get() on a non-object in /mydomain.org/wp-includes/query.php on line
   28).
 * Plugin updates are on auto-pilot via another plugin.
 * Resorted to FTP and deleted the advanced-cache.php file to finally resolve. (
   disabling the plugin manually, then going in through admin, clearing cache, and
   re-enabling did not work).
 * Hope this sticks.
