# Non-persistent cache groups – W3Total Cache?

 * Hi Till,
    Thanks for a great plugin! The last few weeks however I had problems
   saving theme settings (tempera theme) and updating a plugin (Quiz and Survey 
   Master). I found out that the cache of the Redis Object Cache plugin caused that.
   Once I flushed the cache all worked as it should. In another post ([https://wordpress.org/support/topic/theme-options-wont-save-2/](https://wordpress.org/support/topic/theme-options-wont-save-2/)
   you write this: “It’s 100% up to plugin and theme authors to support WordPress’
   object caching functionality. If you’re running into issues it’s best to speak
   directly with them. However if they don’t resolve the issue you can always add
   the cache group they are using to the non-persistent cache groups.” I already
   contacted the theme author, but I have no idea if they are going to do something
   about this.
 * What exactly do you mean by “you can always add the cache group they are using
   to the non-persistent cache groups”?
    And how to do that?
 * The author of the Quiz and Survey master already said that in the future he will
   check his updates first to see if they work with the Redis Object cache plugin,
   so that is good.
 * My second question is: I also have the W3Total Cache plugin working. Also for
   the CDN that I am running. I read in other posts that you don’t recommend to 
   use other caching plugins. But if I remove W3Total Cache what should I use for
   the CDN?
 * Thanks.
 * Johanna

 * You can just add the cache group that Tempera uses for theme options to the ignored
   list by defining this:
 *     ```
       define( 'WP_REDIS_IGNORED_GROUPS', ['counts', 'plugins', 'temperas-group-name'] );
       ```
   
 * You can ask the theme authors for the group name.
 * Using a CDN doesn’t conflict with this plugin. I use Cloudflare for all my sites.
   Just make sure you’re not using W3Total’s caching.

 * Thanks Till.
    I will ask them. As for the W3Total caching, I have disabled Database
   and Object cache, but have enabled the Browser cache. Should I disable that too?
