Unselecting all existing terms

Hi. When I assign terms to a user but then at a later date attempt to remove ALL terms for that user, these changes are not saved, i.e. the function wp_set_object_terms is not called in the code.

By commenting out the following line in the code (line 499)…

if (isset($_POST[$key])) {

all terms are successfully deleted for that user (and any selected terms are saved as expected).

Where all terms are unselected, $_POST[$key] is not set and therefore the argument $term / array($term) in the wp_set_object_terms function is null which is required for effectively deleting all terms.

Cheers
