Thank you very much. I'll send you more info by your contact form on https://metabox.io/contact/

...other situation. By choosing Field Type "Select" I get “Catchable fatal error: Object of class WP_Term could not be converted to string” in the frontend. By coosing Field Type "Select Tree" it works as expected.

The terms are all in the DB. Every thing looks like in the working taxonomies. I did delete this taxonomiy some time ago and made it new. But even if I create new taxonomies it does not work anymore. Allways the same errors as above.

I have no idea where to check it.
