Support » Plugin: Contact Form 7 » Can’t edit page with Contact Form Selector block

  • Since WordPress 5.9 was installed I find that I cannot edit the page where I’m embedding the contact form using the contact form selection block. When I open the page to edit it (not the form, but the page where the form is embedded) I can see the code loading, but nothing but a white screen is displayed.

    If I deactivate the Contact Form 7 plugin, I can go into the page and edit it as normal. Reactivating the plugin allows the embedded form to work normally, but if I try to edit the page where the form is embedded I will get the white screen again.

    If I use the Shortcode block and the CF7 shortcode for the form I want to use, then everything works fine.

    I’m using:
    WordPress 5.9
    Contact Form 7 5.5.4

    Any thoughts on troubleshooting this one?

    What other plugins and theme do you use on the site?


    I got the same error.

    The site config:
    server: Apache
    PHP: 7.4.27
    WordPress version: 5.9
    locale: hu_HU
    active theme: Twenty Twenty-Two 1.0
    (Same error when Astra theme version 3.7.7 is active.)
    Contact Form 7 version: 5.5.4
    WP debug logging is enabled – the log file is empty.

    All other plugins are disabled.

    JS error in browser console:

    Is it possible for you to deactivate all other plugins and try it again?

    Thread Starter macadk


    Yes. I’ll give this a try tomorrow and let you know the result.

    Same error with plain core WP.
    The CF7 block crashes the block editor.
    Shortcode block works.
    Frontend works.
    Please check. This error is ridiculous.
    Thank you.

    Hi I’ve found the same.

    Using WP 5.9 and the Twenty Twenty Two theme, no other plugins active. Initial creation and adding of the block was fine, but reloading the page and just a white screen.

    Error in browser console says “window.wpcf7.contactForms is undefined” and appears to be within /contact-form-7/includes/block-editor/index.js.

    Same error here. I hope this get fixed soon.

    I can confirm two things:

    1) Disabling all but Contact Form 7 has makes no difference. If I use the Form 7 Selector block to insert a contact form on a page, the page works fine on the front-end but crashes the page created using the block editor.
    2) I support what the other posters in this thread have said regarding embedding a short-code for a contact form using the embed block – that works fine.

    It seems that the problem is in the Form 7 block code itself.

    Thank you in advance for your support!

    Thanks for the information.

    I had same issue with the page editor crashing with a CF7 block. Relayed the information needed in a later thread. Rolling back to v5.5.3 and using the default shortcode block solved the issue for me. Thanks.

    I’ve also run into this issue, sometimes I get a blank page, sometimes I get “This block has encountered an error and cannot be previewed.”
