 * Hi,
    we are experiencing problems with the cache. When a user tries to rate a
   post, an error message is displayed. But if we clear site cache the problem is
   gone. We have WP Rocket installed in our site and the cache lifetime has been
   decreased to 12 hours, as a user suggested in a previous topic. Nevertheless,
   we still face the same problem; is WP Rocket compatible with WP Post Ratings?
   is there anything we can do to fix this problem? Any help would be very appreciated.
 * Thanks.

 * Sorry, WP-PostRatings is not compatible with most of the caching plugin.

 * So far it is only [https://wordpress.org/support/topic/support-for-wp-fastest-cache/](https://wordpress.org/support/topic/support-for-wp-fastest-cache/).
   Note that it is not tested by me. So I can’t verify it.
