Meta Box

Hello,

Customizing the permalink settings is beyond the scope of support of Meta Box. You can try to go to Settings > Permalinks > Custom structure > and set it to /%category%/%postname%/.

Or follow this article to customize the permalink with coding https://stackoverflow.com/questions/57765487/how-to-add-custom-taxonomy-in-custom-post-type-permalink
and this topic https://support.metabox.io/topic/post-type-and-then-taxonomy-for-url-structure/#post-40569

Hello,

You can follow the topic below to check if the field is not empty with the Twig code
https://stackoverflow.com/questions/22968427/check-if-string-variable-is-null-or-empty-or-full-of-white-spaces

For example:

{% if post.upload_presentation|trim is not empty %} 
<a class="ct-link-button download-brochure__btn" href="{{ post.upload_presentation }}" download>Download Brochure</a>
{% endif %}

Hello,

The compatibility feature is developed by Bricks team, so I recommend contacting their support for further assistance. Please read more here https://docs.metabox.io/compatibility/

Hello,

Meta Box and WordPress do not have an official option to delete the field value (post meta). You can create a custom loop and delete post meta with the function delete_post_meta() or use a third-party plugin to do that https://wordpress.org/plugins/wp-bulk-delete/

For the custom table mb_relationships, you can access your database and delete all rows in the table.

Hello,

Not yet, I will let you know when it is fixed. Thanks.

Hello Jose,

Thanks for your suggestion. I will inform the development team to consider supporting this feature in future updates.

Hello,

This issue is fixed in this commit a few months ago https://github.com/wpmetabox/meta-box-beaver-themer-integrator/commit/08a1db06918c6bcca77c7a8e01766dee76a7ee59

Can you please check if it is available in the plugin source code on your site?
