For WooCommerce to support any language other than the default (US English), you have to make sure of the following — it doesn’t matter whether you’re on a multisite or single-site install:
-
In the general settings screen (Settings -> General in the admin panel), the Site language should be your desired language. In your case, you should select
Español
. This changes the language WordPress uses to Spanish. -
The localization file (
.mo
) for WooCommerce should be in the correct folder. For WooCommerce, this iswp-content/langauges/woocommerce
. The file name iswoocommerce-[locale].mo
. You can download the.mo
-file for your language on WordPress.org. Click on the percentage in the Stable column for your language and export the language.mo
-file on the bottom of the page (.e.g https://translate.wordpress.org/projects/wp-plugins/woocommerce/stable/es/default).The downloaded file should be renamed and placed in the aforementioned folder, yielding
wp-content/languages/woocommerce/woocommerce-es_ES.po
in your case.
