Help! Links not working in translated shop

If you have updated for the latest versions of Woocommerce and WordPress, the localization/language management of the themes/plugins has changed for the latest updates.
And, the Codestyling Localization plugin is not updated for more than 1 year; so it is a bit out-dated.

Basically, the “directory” to put the language files is changed.
It is no more inside the Woocommerce directory:
https://www.yoursite.com/wp-content/plugins/woocommerce/i18n/languages/woocommerce-xx_XX.po

it is now inside an up-level directory:
https://www.yoursite.com/wp-content/languages/plugins/woocommerce-xx_XX.po

You can use the new translation packs, or PoEdit to create/edit your own localization files.

Thank you very much for your answer! Could you, please, tell me step by step what exactly I have to do or send me some link, where I can find the instruction? I am not so fluent with all these terms, and find myself a bit lost. I would greatly appreciate your help.
