Message:

Twenty Fourteen: Fix fatal errors in WordPress versions before 4.0.0

The line of code throwing the error was introduced in WordPress 4.5 in r37040 "Customize: Require opt-in for selective refresh of widgets". Since is_customize_preview() was introduced in 4.0.0 and Twenty Fourteen should work from WordPress 3.6 and up, this caused the issue.

The patch adds an is_customize_preview function if it's missing.

Props adamsilverstein.

Fixes #39407.
