Cannot Edit Global Blocks in Pro

[SJF_me]

I am getting a message that says: “The preview could not load due to the iframe response being incomplete. This is most often related to a plugin conflict, or customizations introducing a PHP error.”

I’ve disabled all plugins and made sure Pro is up to date but still no luck. I’ll include a screenshot and credentials in a private note.

Hi @SJF_me,

Thanks for reaching out!

I just check your website and confirmed your issue but upon investigating the Global Blocks are not accessible, I found out that it is your child theme causing the issue. When I tried to activate the parent theme, we can now edit the Global Blocks. Please note that we don’t support any customization made in the child theme.

Hope that helps.

Thank you @marc_a! I didn’t even consider the child theme being the culprit. I’ve narrowed it down to this specific function:

function lets_redirect_404_pages() {
    global $wp_query;
    if ( $wp_query->is_404 ) {
      wp_redirect( get_bloginfo('wpurl'), 301 );
      exit;
    }
}
add_action('template_redirect', 'lets_redirect_404_pages', 1);

Thanks for your assistance!

Quick follow-up question. Should I be avoiding anything in particular in that above code snippet to avoid conflicts with the Pro editor? I can’t seem to see what exactly would’ve caused the issue, and I would like to try to avoid writing any potentially conflicting code in the future.

Hi @SJF_me,

You can add !is_admin() clause into the if to avoid this code run into the Admin section.

if ( $wp_query->is_404 && !is_admin()) 

Hope it helps.
Thanks
