Woocommerce germanized

Hallo,

ich habe das Plugin Woocommerce germanized auf die Version 1.6.8 aktualisiert. Die Wordpress-Version ist 4.5.3

Nun bekomme ich folgende Fehlermeldungen:

Warning: Unexpected character in input: '\' (ASCII=92) state=1 in /homepages/24/d216710303/htdocs/wp-content/plugins/woocommerce-germanized/includes/api/class-wc-gzd-rest-customers-controller.php on line 176

Vielleicht kann mir jemand weiterhelfen was das nun bedeutet?

Danke & Grüße, Sabine
