Woocomerce language

This is pretty common issue with translations. If you have downloaded po/mo woocommerce translation files, you probably put them now in wp-content/woocommerce/languages folder. Please if this is the case try to move them to global languages folder in wp-content/languages/plugins. Also note that if you are moving them to global folder they should look something like this: woocommerce-YOURLANG.mo and po files as well. In your case it would be something like woocommerce-lt_LT.mo or woocommerce_LT (I am not very sure about your language codes, you should know that). Also refer to woocommerce documentation for translating as it might help you a lot here -> LINK

If in some case woocommerce is not translated to you language I would advise you to use LOCO TRANSLATE plugin to do so for yourself, at least for necessary strings.

I hope this helps.

Kind regards,
