Hi Rui,
Thanks for your reply. I tested to call load_child_theme_textdomain() both inside a custom function and to call it directly as you suggested. It doesn’t work in both ways.
We have 2 main issues:
1) .po .mo files are not loaded from my child theme “Salugea”, it uses default theme translation files
(to test it you can rename “.po .mo” to “.po.default .mo.default” on /atelier/languages/ and you will see product purchase button “Aggiungi al carrello” to become as default “Add to cart” – check product box on my homepage right after main image with green leaves)
2) when I edit .po file with Poedit I need to validate some rows – those rows are highlighted in gold. After validating those rows and uploaded .po .mo files on /language dir all theme options labels on WordPress will become translated as “theme options” > “opzioni tema”
I hope you can understand what is happening
regards
Marco
