Changeset 31681 for trunk/src/wp-includes/theme.php

Timestamp:

Message:

There are a few functions that have the ability to return false instead of a string, so the return value should be checked before being passed to functions that expect string.

These are trivial, but they clear out some Scrutinizer issues.

See #30799.
