 * Hello, the Zencache update I performed today blew the site. The only way to get
   back in was to use FTP and rename the plugin folder. I let it sit for a while,
   then I went back and tried to get it back working and it blew the site again.
   So it’s still Zencache-OFF right now. Any solution?

   We’re currently investigating an issue that appears to be a PHP bug (not a bug
   with ZenCache itself but rather with the server-side software that runs ZenCache
   and WordPress itself). For now, if you need to get ZenCache running on your site,
   we recommend downloading and installing the previous version ([download v150409](https://downloads.wordpress.org/plugin/zencache.150409.zip)).
 * If you could, one thing that would be immensely helpful to us in debugging this
   issue would be if you could tell us the PHP Version and APC Version that your
   server is currently running. Here’s how you can get that information:
    1. Install the [WordPress phpinfo()](https://wordpress.org/plugins/wordpress-php-info/)
       plugin
    2. Visit **WordPress Dashboard → Settings → WordPress phpinfo()**
        At the top of
       that page it should say “PHP Version”, with a version number–that’s the version
       number we need.
    3. If you then search that page for “apc” or “APC Support”, you should find the
       APC section along with a version number (possibly 3.1.9 or 3.1.13); we need 
       that version number as well. (Note: If your server doesn’t have APC Support 
       enabled, you might not find any section called “APC” on the page.)
 * If you could let us know those two version numbers, that will help us diagnose
   this problem. Thanks so much!

   Thanks so much for those details! One more question: When you say that ZenCache‘
   blew the site’, was there any error message that showed up?

 * Same thing here. No errors, just blank page. I renamed the plugins/zencache directory
   and the website started working again.
 * To be sure that was zencache update, I enabled it again and the website crashed
   again. So it’s disabled for now.

 * [@carolcomandulli](https://wordpress.org/support/users/carolcomandulli/) Would
   it be possible to follow the steps I outlined above and tell me which PHP Version
   and APC Version you’re running on your site?
