I first saw it on version 5.8.6 but I updated it to 5.8.7.
I am not using this function.The code that breaks is part of the advanced custom fields plugin. I understand what goes wrong but i do not know how to fix it in my site if it the error is in the plugin. To be honest, I don’t see the added value of the function acf_is_empty.
<?php
if( ! class_exists('acf_field_flexible_content') ) :
class acf_field_flexible_content extends acf_field {
......
// bail ealry if no name (tab)
if( acf_is_empty($sub_field['name']) ) continue;
Hello John,
This is part of the acf plugin. I added the file where this happens it is on line 766.
