We have a frontend form with a taxonomy field. The taxonomy field is breaking the form and stops anything after that from loading. Not the rest of the form or anything else on the page.
Changing the type to taxonomy_advanced did NOT fix it.
Changing the field_type from select_advanced to select did NOT fix it.
Removing the field from the fields array DID fix it.
The field works fine in WP admin.
This issue is relatively recent, perhaps with the latest version.
We're using Metabox AIO.
