It seems there are 3 files which are still outdated. If those files aren’t modified by the Theme, should I manually copy the woocommerce templates files and replace these 3? or if you have an update, could you provide us with these updated files?
Site URL: hidden Theme version: Legenda 4.2 WooCommerce version: 3.8.0
Legenda theme does not have these files, you can download an archive of the theme and check.
These files are placed in your child theme, so likely, contain your custom changes. You need to compare files (your files and files of WooCommerce plugin) and add the missing code to the child theme files.
