Meta Box

Thanks, unfortunately, the sidebar is no good for me. I have found a discussion about the issue here: https://github.com/WordPress/gutenberg/issues/69923

It looks like it's not going away any time soon.

I've figured out the 'Text' issue, I found some code I'd previously written. There should be an options array as below

    'options'  => [
         'raw' => true,
    ],

This option is not mentioned in the WordPress docs linked from the Metabox docs.

I have deleted the AIO plugin and installed the lite plugin, plus just the two extensions I need, but I still cannot duplicate the cloneable group.

My fault, I'd inadvertently changed the name of the rwmb_meta_boxes filter, so nothing was running…

It looks like any time I include an image advanced field this code appears. I'm enabling them as shown below, have I missed something. I don't have this happening on any other site.

    $meta_boxes[] = array(

        'id'			=> $prefix . 'header_gallery',
        'title'			=> esc_html__( 'Header Gallery', 'dlf' ),
        'description'	=> esc_html__( 'Sliding images in the header', 'dlf' ),
        'post_types'	=> array( 'post', 'page' ),
        'context'		=> 'normal',
        'priority'		=> 'high',

        'fields'     => array(
            array(
                'name'	=> esc_html__( 'Images', 'dlf' ),
                'id'	=> $prefix . 'header_imgs',
                'desc'	=> esc_html__( 'Scrolling images at the top of the page', 'dlf' ),
                'type'	=> 'image_advanced',
            ),
        ),
    );

I can confirm that I don't have Front End submission installed (not using AIO). If I switch to 2021 Theme it doesn't show, but then that theme doesn't use Meta Box, so I wouldn't expect it to.

Actually, having looked at another site of mine, the 'Custom class' field seems to have been added by a plugin (probably foogallery). I'll have to look into it.

Sorry, still not working for me: https://boltwood.online/hosting/tmp/5-check-again.png

It was the official plugin, but don't worry, they've fixed it now: https://wordpress.org/plugins/font-awesome/#developers
