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?
