I have a custom post type with a custom taxonomy using this plugin. The following code is used to edit the taxonomy:
<?php the_terms( $post->ID, 'specialties', '', ''); ?>
When I hover over the list, the edit button appears, and I can click it to edit. However, once I'm editing, there is no way to save the edits. The Save/Cancel button doesn't not appear anywhere. If I hit return or tab out of the editor box, nothing happens.
If I recall, this issue was not present in the earlier development of this site. Did it break after an upgrade, by chance?
