Hi, I created a custom frontend form using the ACF tutorial. It’s working for all custom fields except for the file upload field. When I turned on bug tracking, here’s the errors I’m getting:
Notice: Undefined index: url in /home4/chrisve7/public_html/dev/wp-content/plugins/advanced-custom-fields-pro/includes/api/api-helpers.php on line 3766
