Custom Taxonomy not listing options in post editor

When you click the “Console” tab, are you seeing any error message that look related at all? I feel like there’s some sort of javascript conflict going on that’s preventing things from loading here.

Screenshot of console tab.

Hmm. Not much at all to go off of there.

If you go to the CPTUI tools menu and click the “Taxonomies” tab, you can get a copy of your taxonomy settings, it’ll be the blob of text on the right. Paste it here and I can import those to my local install to see if I can recreate with exactly what you have for settings. May provide some more insight than I can get from screenshots alone.

Thanks for the help. Note also that this issue doesn’t occur with the gutenburg editor. It’s in the classic editor and/or the Avada editor that the issue occurs. And again, it’s only the “sources” taxonomy that has the issue, my other custom taxonomies load fine in any of the editors. So it’s something specific to that taxonomy.

Good morning,

Looks like this is the culprit: "meta_box_cb":"post_sources_meta_box". You’re specifying a value in the Metabox callback field, but are potentially not creating a function by that name to handle rendering the content. Unsure if that was an accidental value added, or perhaps a previous test by someone that was forgotten to be removed. If you remove it, leave that field blank, and save, then WP core resumes responsibility to render things and you’ll be back in business.

One reason why things were fine with Gutenberg is because that editing experience doesn’t pay attention to anything specified for meta_box_cb

Thank you! That did the trick! Not sure where that field entry came from.

Welcome ??
