    Hi

    I am getting this error

    [19-Nov-2025 10:26:57 UTC] PHP Warning: Undefined array key "post_fields" in /wp-content/plugins/meta-box-aio/vendor/meta-box/mb-frontend-submission/src/Integrations/Bricks/SubmissionForm.php on line 253

    Caused by this line in SubmissionForm.php

    'post_fields' => implode( ',', $settings['post_fields']),

    I know it can be resolved by changing the line to the below but obvs it gets overwritten when the plugin updates, is this a MetaBox or Bricks thing?

    'post_fields' => implode( ',', $settings['post_fields'] ?? []),

    Is there some way in the form to prevent this?

    Hello Emma,

    Thanks for your feedback.

    It is an issue with Meta Box. Let me escalate this issue to the development team to fix it in the source so it won't happen again.

    Hi
    Thanks for that
    Unfortunately the plugin has updated today and brought the site down again.
    Do you have an ETA on that fixed being implemented?

    Hi

    The latest update brought the site down again which is a little frustrating my me and my customers

    Could you please fix it before the next update it really is just a case of replacing line 253 in SubmissionForm.php with this code to provide a fallback id 'post_fields' is not supplied

    'post_fields' => implode( ',', $settings['post_fields'] ?? [] ),
