Meta Box

Thank you!
The enqueue_block_editor_assets hook is what I am using now. Code Example:

function _akdev_mbBlockScripts()
{
    wp_enqueue_style(
      '_akdev-ctaBlock',
      get_template_directory_uri().'/inc/mb-block-templates/cta.css',
  );
}
add_action('enqueue_block_editor_assets', '_akdev_mbBlockScripts');

Hi,
I think there is a misunderstanding here. I get these Errors inside the Contact Form 7 Plugin doing this in the WordPress Admin area:

Click on

1. Contact
2. Add new
3. Save

Theme is Twentytwentyone, active Plugins are: Meta Box, Meta Box AIO, Contact-Form 7

Thx for your feedback,

I deactivated all plugins that are not Meta Box and switched to a different theme. No Error there. After activating my theme and my plugins again, everything is okay.

the gif is to fast, this one should visualize it better https://ibb.co/1LD8D2q

Thank you for the reply, I got stuck on how to get a true/false value for the callback. I will try this.
