Hello,
Thanks for contacting us and sorry for any inconvenience that might have been caused due to that.
I checked and figured out that the issue is being caused by the Advanced Custom Field PRO plugin. If you deactivate the plugin, the meta box works fine.
You are using an old version of ACF PRO and you also haven’t activated the license of this plugin. Please update it to the latest version and that should fix the issue.
Hope this helps. Let us know if you need any further assistance.
cảm ơn bạn tôi đã khắc phục được sự cố này.
