    When I try to load the /wp-admin/customize.php page, the page is blank. Why?

    I just did a fresh install of wordpress in a VM running Debian 10. I did not install any plugins (though wordpress came with Akismet Anti-Spam
    installed by default). I have the latest version of WordPress from the
    debian repos installed — currently that’s 6.1.6 (which is listed as
    supported by this theme at the time of writing). WordPress is served by nginx 1.22.1 and php8.2-fpm. I’m using the latest version of this theme (downloaded yesterday) = v3.8.7.

    I’m using firefox 115.11.0esr and accessing the wordpress site at https://localhost:8081/

    When I click on Appearance -> Customize, I get an empty page.

    There are no PHP or web server errors appearing in the nginx logs.

    There are numerous errors appearing in the javascript console:

    Some cookies are misusing the recommended “SameSite“ attribute 2This page uses the non standard property “zoom”. Consider using calc() in the relevant property values, or using “transform” along with “transform-origin: 0 0”. customize.phpLayout was forced before the page was fully loaded.

    If I change the theme to the only other theme installed (the default = Twenty Twenty-Three that came with wordpress), then I can load the customize.php page without issue.

    Where can I report this bug?

  • Hi,

    Thank you for sharing this.

    Can you please let me know how you’ve installed Neve? Did you download it and then upload it as a zip?

    If that’s so, can you please try install it from Appearance > Themes > Add New Theme > search for Neve and Install & Activate.

    Other than that, please try with other more complex themes as well, for example Astra, OceanWP or Kadence and let us know how that goes.

    Kind regards,

    let me know how you’ve installed Neve?

    Download .zip with wget, scp to server, unzip in wp-content/themes/ folder

    can you please try install it from Appearance > Themes > Add New Theme > search for Neve and Install & Activate.

    I cannot.

    For security reasons, wordpress config is set with WP_HTTP_BLOCK_EXTERNAL. Moreover, our firewall blocks the web server from being able to initiate requests. To install plugins and themes, we use scp and ssh.

    define( 'WP_HTTP_BLOCK_EXTERNAL', true );

    Hi,

    Ok, I understand.

    Probably some of these server configurations are causing the errors in Customizer.

    You can try with other themes as well to see if there is any difference.

    Unfortunately, I’m not able to help here anymore. You can check with your hosting provider if there are any changes you can do to the server, if this is what you want.

    Kind regards

    Our server is a VPS (though currently I’m just testing on a VM on my laptop). Anyway, I am the admin responsible for the server’s configuration.

    This security hardening is intentional. It’s a best-practice feature that’s built-into WordPress. It shouldn’t cause any issues to install the theme the traditional way with scp.

    I reported the bug here:

    Hi,

    Ok, thank you for the update.

    I’m looking forward to see what the dev team will share about this.

    Have a great day!
