Support » Plugin: Simple Fields » clear_caches causing WSOD

  • I’m running WP 4.3 on PHP5-FPM, Nginx + Varnish.

    Adding a new post, or saving an existing post in admin results in the WSOD. I’ve narrowed it down to the following hook:

    add_action( 'save_post', array($this, 'clear_caches') );

    Enabling WP_DEBUG doesn’t give me any additional details.

    Any idea what to look for?
