Imported posts and terms but terms not appearing on the frontend

I created a giant import that grabbed both taxonomy terms and posts from a different application. To import the terms I used wp_set_post_terms( $post_id, $term_ids, 'my_taxonomy' ); which works because I see them on the edit screen for each post.

However, when I go on the frontend and look at my post the terms are empty. If I go back on the edit screen and just click on "Save" then they finally appear on the front end.

I have close to 2,000 records and doing this manually would be quite unwieldy and I can’t for the life of me figure out what happened! How do I force this update across the board programmatically?

I’ve tried using both clean_term_cache(); and clean_object_term_cache(); and it didn’t seem to make a difference. Maybe I’m calling these wrong but it’s not doing a thing as far as I can tell.

I’ve tried:

• clean_term_cache
• clean_object_term_cache
• delete_option($tax.’-slug_children’);
• delete_option($tax.’_children’);
• clean_taxonomy_cache($tax);
• wp_cache_flush();
