Hello,
You need also translate Woocommerce .po file in the directory wp-content/plugins/woocommerce/i18n/languages. There you’ll find “Product Description” text.
Please refer to Woocommerce documentation: http://docs.woothemes.com/document/woocommerce-localization/
“Oops! Page not found” text can be found in the .po file in wp-content/themes/theleader/languages.
Please check it carefully.
Regards,
Eva Kemp.
