  Hi @leonho

  Thanks for the error reports. I’m looking at the issue:

  
  /wordpress/wp-content/plugins/advanced-custom-fields/core/controllers/input.php 178 calling apply_filters()
  

  But that line of code reads:

  
  $acf['options'] = apply_filters('acf/field_group/get_options', array(), $acf['id']);
  

  This looks pretty normal to me. Can you spot the issue?

  I think the warning is from the line:
  /wordpress/wp-content/plugins/advanced-custom-fields/core/controllers/field_group.php 62 calling wp_cache_get()

  Hi @leonho

  Thanks mate, looking at this line, ACF looks like:

  
  $found = false;
  $cache = wp_cache_get( 'field_groups', 'acf', false, $found );
  

  Can you confirm this is what you see? Are you running the latest ACF 4.1.8.1?
