Just a words to thank Rexchances his solution and say that, since I put my .mo . po files in the woocommerce folder, they have not been changed and everything is working smooth…
New .po and .mo files have been auto-created again at wp-content/languages/ folder, but the ones in use are those in Woocommerce folder, so will live with that. Only I’m sorry because this issue doesn’t let me use LoCo to make translations on the fly.
Tonight I’ve received WooThemes answer to my request:
“Can you tell me exactly what folder you are uploading your edited .po & .mo translation files to? Is it /wp-content/languages/woocommerce? If not, try uploading your .po & .mo files in that folder and let me know if the issue remains.
I hope that helps!”
So I think they don’t know what happens but point to your idea too…
Best regards and thank you all very much,
Raúl.
