Changeset 35851 for branches/4.4/src/wp-includes/category-template.php

Message:

Improve handling for WP_Error objects in get_the_terms().

wp_get_object_terms() can return a WP_Error object. As such, the
get_the_terms() cache wrapper should handle them properly. To wit:

• Don't try to map an error object to get_term(). Introduced in [35032].
• Don't cache an error object as taxonomy relationships. Introduced in at least [16487], maybe earlier.

Ports [35850] to the 4.4 branch.

Props stephenharris.
Fixes #34723.
