# pdb_record data ‘delay’

 * Hi,
 * A bit of an odd one.
 * If I create a new record in the back-end (wp-admin), the record is added to the
   database without issue. However, the new record is not displayed using the pdb_record
   template for a ‘period’ of time (2mins – 1 hour); it is immediately displayed
   in pdb_list and pdb_single templates. If the pdb_signup template creates the 
   record through the frontend, everything works as it should.
 * I’m guessing there’s nothing wrong with the code as it works eventually, and 
   assuming it’s a WordPress Themes issue, but I (and those I have asked) haven’t
   seen this before.
 * Any help would be gratefully received. TIA

 * This is most likely due to some form of caching. This is most likely a plugin,
   these usually don’t cache for logged-in users.
 * You need to clear the cache to see the fresh content, alternatively you can exempt
   the page from caching.

 * Hi Roland,
 * Thanks for the very quick reply.
 * I have already disabled caching via the wp-config.php file but the issue remains…

 * Keep looking, that is not the only way caching is controlled. Probably it’s a
   plugin.

 * I have a comparable problem. When I update the Participants db by a script that
   runs outside of the Participantsdb plugin, in many cases I have to wait 24 hours
   before the results are visible via the plugin. I have seen that the plugin has
   its own cache that is by default set to a DAY (in the PDb_Participant_Cache class).
   In the Settings of the plugin there is no way to clear this cache or to set its
   expiration time. This would be a very helpful feature.

 * So, for the original poster of this thread [@helitraxuk](https://wordpress.org/support/users/helitraxuk/),
   this cache is cleared automatically when a record is updated, either on the frontend
   or the backend, so this is not the problem you are seeing. If you have Participants
   Database debugging on, you will see the cache clearing message in the log.
 * [@thomaswesselplace](https://wordpress.org/support/users/thomaswesselplace/):
   This is automatic when a record update happens using the `Participants_Db::write_participant`
   method, but you can invalidate the plugin’s internal cache for the specific record(
   meaning the record data must come from the database next time it is displayed)
   using this method call:
 * `PDb_Participant_Cache::is_now_stale( $record_id );`

 * Hi Roland,
 * Is this the cache clearing message you are referring to? It’s the only caching
   message listed in the log;
 * > PDb_Participant_Cache::refresh_cache: Refreshing Participants Database cache
   > for cache group 0

 * Yup, that’s it. The cache is kept in groups of 100, so that indicates the cache
   for the first group was cleared: record ids from 1 to 100.
