    Hi there,

    when I try to edit some of my Custom Field Groups, I get an error message: Something went wrong. Please try again!

    Console says: [Error] SyntaxError: '#603554e9c31e3' is not a valid selector.
    querySelector
    (anonyme Funktion) — 4522.app.js:1:684

    Perplexity suggests this:
    We can reproduce a builder crash when editing multiple custom field groups in Meta Box AIO.
    Our field-group JSON uses valid IDs only, for example nd-gallery-news-field-group and field IDs like nd-gallery-news-content.
    However, the builder throws SyntaxError: '#603554e9c31e3' is not a valid selector, which suggests Meta Box generates an internal element ID starting with a digit and then passes it unescaped into document.querySelector().
    After that, a secondary error appears: TypeError: null is not an object (evaluating 'document.querySelector("#post_title").removeEventListener').
    This looks like a Builder/React frontend bug rather than a field schema issue. Please check whether internal IDs should be escaped with CSS.escape() or accessed via getElementById() instead.

    Best JC

    Hello,

    Thanks for reaching out.

    Can you please share the field group JSON files with me so I can reproduce the issue on my site? Also, please share the steps you take on your site to see the error.

    When I click on "edit" in the CFG list in the WP dashboard I see the editor for a very short time. Then this error:

    ERROR: null is not an object (evaluating 'document.querySelector("#post_title").removeEventListener')

    Some other CFGs open the editor just fine.

    Hello,

    I import your field group to my demo site, edit the field group but don't see any errors. Screenshot https://imgur.com/UfAtwMZ

    I will take a look.

    Problem solved. Thank you Peter. If someone has the same issue: try export, delete and re-import of the custom field group.
