    Just attempted update to BackWPup 3.3.6 and resulted in error near top of admin pages:

    Warning: Unexpected character in input: ‘\’ (ASCII=92) state=1 in /…/wp-content/plugins/backwpup/inc/class-admin.php on line 528

    The line in question reads:

    if ( $screen instanceof \WP_Screen ) {

    I changed it to the following without error:

    if ( $screen instanceof WP_Screen ) {

    Was this the right course of action? Has anyone else seen this error?
