If you are trying to translate the WooCommerce Subscriptions plugin using WordPress’ free Codestyling Localization plugin, you are probably encountering problems.
That’s because Codestyling Localization’s support for translating the plural forms of words is buggy. This is bad because the WooCommerce Subscriptions plugin uses singular and plurals of words for billing terms like month/months.
But don’t fret: WooCommerce Subscriptions can be translated just fine using the WordPress Multilingual Plugin– available for just $15 on WPspring.
