# Issues with Redis Object Cache

 * Hi there. It appears that your plugins (Perfect Images, Media Cleaner, and Database
   Cleaner) do not work well together with the [Redis Object Cache plugin](https://wordpress.org/plugins/redis-cache/).
 * We recently installed Redis Object Cache, and since then, we have been noticing
   a bunch of issues associated with Perfect Images and Media Cleaner. In fact, 
   we had to deactivate Perfect Images, because it only showed a white screen on
   the settings page. No actual settings at all. Reactivating it did not fix the
   problem.
 * After noticing some slowness and investigating using Query Monitor, we saw lots
   of delete_option() calls. We also noticed this before we deactivated perfect 
   images. And as I write this, all of our settings on the Media Cleaner Pro settings
   page have been wiped out.
 * From Query Monitor, here’s how the call looks like:
 * `delete_option()
   wp-includes/option.php:737Meow_WPMC_Core->check_options()wp-
   content/plugins/media-cleaner-pro/classes/core.php:1307Meow_WPMC_Core->get_all_options()
   wp-content/plugins/media-cleaner-pro/classes/core.php:1272Meow_WPMC_Core->get_option()
   wp-content/plugins/media-cleaner-pro/classes/core.php:1266Meow_WPMC_Core->plugins_loaded()
   wp-content/plugins/media-cleaner-pro/classes/core.php:39do_action('plugins_loaded')
   wp-includes/plugin.php:517
 * The page is: wp-admin/admin.php?page=wpmc_settings&nekoTab=advanced
 * In the actual Query tab, there’s something like this:
 * `SELECT autoload
   FROM wp_optionsWHERE option_name = 'wpmc_content'
 * This is repeated many times with different values for option_name.
 * We are also pro users of your Database Cleaner plugin. Never had an issue updating
   in the past. But today (after setting up Redis Object Cache yesterday), we tried
   updating Database Cleaner Pro and got the following error:
 * An error occurred while updating Database Cleaner: Clean, Optimize & Repair (
   Pro): **Download failed. cURL error 56: OpenSSL SSL_read: error:0A000126:SSL 
   routines::unexpected eof while reading, errno 0**
 * Other unrelated plugins have updated well.
 * This is only partly a support request. We want you to be aware of these issues
   as well. We don’t want to go opening multiple support requests across the different
   plugins.
 * If you have a quick solution based on the details provided please let us know.

 * **Update: **The delete_option() calls are actually happening on any admin page(
   like the main admin dashboard). Not just on the Media Cleaner settings page. 
   This is an ongoing problem, and we may have to temporarily deactivate Media Cleaner
   as well (until we know what’s going on) before this ends up deleting useful content.
 * Using Media Cleaner, on our WordPress admin page, I filtered queries by caller
   where caller is delete_option() and there where 88 such calls! All with a different
   option name.

 * Hi,
 * I am going to investigate; but don’t worry, it’s not going to erase your own 
   options. I moved from many options to only one option to handle every settings
   in Media Cleaner, so it might be linked to the cleaning that always happens (
   but normally, it shouldn’t).
