Object Cache, save_post action, and ACF repeater fields

Replies: 0

Hi,

I’m seeing what appears to be a compatibility issue between W3 Total Cache 0.9.5.2 and Advanced Custom Fields Pro 5.5.10. At the time of writing these are both at their latest versions. I have a repeater type field with sub fields which are not populated with the saved data during a save_post callback, priority 10 or higher. If I disable W3TC, or specifically the W3TC object cache (Memcached or Disk), I can access the repeater fields in the save_post callback but when the object cache is enabled the fields always return empty.

Because of a limitation with the environment that I’m working in I need access to the repeater fields in the save_post callback.

Has anyone else run into this issue and have you found a fix?

Thanks!
