Comment (by earnjam):

 Looks like the changes to `wp-settings.php` in [44524] stepped on the
 `$theme` global.

 {{{#!php
 <?php
 // Load the functions for the active theme, for both parent and child
 theme if applicable.
 foreach ( wp_get_active_and_valid_themes() as $theme ) {
         if ( file_exists( $theme . '/functions.php' ) ) {
                 include $theme . '/functions.php';
         }
 }
 unset( $theme );
 }}}
