First I used the free version of ACF. After installing ACF Pro I received this message when I tried to open an existing post or when I tried to make a new post in WP:
Fatal error: Call to undefined function acf_get_field_group_visibility() in /…/wp-content/plugins/advanced-custom-fields-pro/forms/post.php on line 202.
Can you help me?
