Translation of the form fields in checkout page

Hi,
Having exactly the same problem! Checkout fields remain in English despite I’m using the Finnish translation. They are marked the right way in the po file, so that’s not the problem. Is there a fix for this?

You can wait and see if Woo will update the language files, but if you don’t want to wait, various background reading and methods, including a plugin, are here.

Here is one method. I am using Spanish as an example.

Bring up wp-config.php in a text editor and look for the line:
define(‘WPLANG’, ‘es_ES’);
This will give you your language identifier, in this case its “es_ES”

Go to wp-content/plugins/woocommerce/i18n/languages
and look for:
woocommerce-es_ES.po
Rename it with a .txt extension so you can edit it.
Add a pair of lines at the end for each form label translation. The first is the English that appears now, the second line is the translation in your language. For example:
msgid “Company Name”
msgstr “Nombre de compañía”

Change the file back to .po and download it to your hard drive.
Compile your .po to .mo using this tool:
http://po2mo.net/
The converted filename might be:
h5673b_woocommerce_es_ES.mo
change it to
woocommerce-es_ES.mo
Ensure you get the underscores and hyphens right.

Upload the .mo to
wp-content/plugins/woocommerce/i18n/languages
overwriting the file that was there.

If you have a page caching plugin, delete cached pages.
