WP's preview functionality broken by this plugin as of WP v6.4 #1546

Issue Overview

As long as any metaboxes are defined for a given post type, posts of that type can't be previewed from the Gutenberg editor. A new tab opens, and you'll be redirected to /wp-admin/undefined.

Disabling the plugin, or just removing any add_filter('rwmb_meta_boxes'... calls restores WP preview to a working state.

A similar issue has been raised on the official metabox support forums as well. Note that I'm experience this bug on ALL posts, not just those with custom post types. https://support.metabox.io/topic/impossible-to-preview-posts/

Steps to Reproduce (for bugs)

  1. Enable plugin
  2. define any metabox
  3. try to preview a post of the type that metabox is defin
  4. get redirected to /wp-admin/undefined

This happens in chrome, ff, and safari. I assume it is browser agnostic.

Hi @jacobph ,

Thanks for your feedback. We're investigating into this issue and narrowing it scope. We find that the validation module causes this bug and working on that. We'll update soon.

Hi @jacobph ,

We've fixed this bug in 955e6a0 and will update the plugin soon. We're working on 2 small PRs which probably takes 2 days to complete. After that we'll update the plugin.

Thanks for your feedback.
