Support Meta Box Conditional Logic Settings Pages + Conditional Logic breaks Oxygen editor widget functionality

    Metabox conditional logic and settings pages seems to be causing an issue with Oxygen admin ajax. The line referenced in one of the errors points to a Gutenberg integration function in conditional logic extension. Whatever it is, it’s causing Oxygen to fail every time I enable metabox conditional logic extension and have a settings page built with metabox settings page extension.

    Steps to reproduce:
    1. Install MB core
    2. Install AIO, enable Settings Pages/Conditional Logic
    3. Add the settings page sample code from
    4. In the Oxygen editor add a > Basics > ‘Section’
    5. Inside the section add a > WordPress > Widgets > ‘Navigation Menu’

    Expected behavior:
    The widget settings should load in the Oxygen side panel and the widget should be displayed in the editor window.

    Actual behavior:
    Widget settings display a spinning wheel or an error message, widget doesn’t load in Oxygen editor window.

    Error messages:

    • Chrome dev tools –
      Failed to load resource: the server responded with a status of 500 (Internal Server Error)
    • Oxygen editor –
      Fatal error/exception
      File: /wp-content/plugins/meta-box-aio/vendor/meta-box/meta-box-conditional-logic/conditional-logic.php
      Line: 69
      Plugin: meta-box-aio

    I’ve got a sandbox site I can give access to or I can zip up a copy of the entire site and send it. Link to sandbox:

    The Oxygen page builder is the premium plugin, so please share a copy of this plugin with the contact form I will check this plugin on my local site and give a quick response.


    @Long Nguyen, any updates on your findings with this? I’ve submitted tickets with Oxygen also, so if you discover anything related to their plugin, please let me know and I’ll get on their case about it.

    This is a new plugin page builder, so we need some days to research and check the compatible of this plugin and Meta Box.

    I will inform you if there is any information.


    OK, I got a response from Oxygen support, and since the error is coming from your file, they are pretty sure it’s your problem…


    Any progress on this issue yet?

    We’ve just released a new version of Meta Box AIO v1.11.9 to cover this case, please update the extension and recheck the issue.


    Thank you so much. This seems to have fixed my issue!
