# Getting ‘Filesystem: Not writeable’ error in version 2.5

 * First off, thanks for developing and maintaining this terrific plugin. I’ve been
   using it for years, and it makes a huge difference on our sites.
 * I have an issue with version **2.5** by which I’m a little confused. When I look
   in the plugin’s settings, I see that it says `Filesystem: Not writeable`. This
   wasn’t happening prior to **2.5**. Fortunately, this change doesn’t actually 
   stop the plugin from working, but it _does_ prevent the `Disable Object Cache`
   button from working.
 * I can see from the [changelog](https://wordpress.org/plugins/redis-cache/#developers)
   that the system is trying to write two files: `object-cache.php` and `object-
   cache.tmp`. If I look on the server, I can see that `object-cache.php` is there,
   and, moreover, that it’s being written by the latest version of the plugin. I
   know this, because, at the top of the `object-cache.php` file, it confirms that
   it’s version 2.5:
 *     ```wp-block-code
       <?php
       /**
        * Plugin Name: Redis Object Cache Drop-In
        * Plugin URI: https://wordpress.org/plugins/redis-cache/
        * Description: A persistent object cache backend powered by Redis. Supports Predis, PhpRedis, Relay, replication, sentinels, clustering and WP-CLI.
        * Version: 2.5.0
        * Author: Till Krüss
        * Author URI: https://objectcache.pro
        * License: GPLv3
        * License URI: http://www.gnu.org/licenses/gpl-3.0.html
        * Requires PHP: 7.2
       ```
   
 * Nevertheless, the plugin seems unable to write the other file (`object-cache.
   tmp`, and, thus, it concludes that the filesystem is `Not writeable`. I’m unsure
   as to why this would be the case. Surely, if the plugin can write `object-cache.
   php` to the correct folder, it can also write the `.tmp` file? The permissions
   on the `WP_CONTENT_DIR` are 775.
 * I am using [Trellis](https://roots.io/trellis/) and [Bedrock](https://roots.io/bedrock/),
   and I’m enabling the plugin using wp-cli, so the file structure and setup of 
   my WordPress install is a little different than the out-of-the-box version, but
   this has never mattered before.
 * Any thoughts or advice as to where I should look?
 * Thanks!

 * Hey Charles!
 * If `WP_CONTENT_DIR` is set to `775` the wrist test _should_ work.
 * However if you use WP CLI anyhow to successfully enable the cache using `wp redis
   enable` then you can safely ignore the check by setting:
 *     ```wp-block-code
       define('WP_REDIS_DISABLE_DROPIN_CHECK', true);
       ```

 * Thanks, Julie. Out of interest, what does that do?

 * It will just skip that test and not bother you with an unnecessary warning.
