I am trying to override Woocommerce's templates files by duplicating them in my custom theme directory / woocommerce / templates, but the changes don't appear (I tried simply adding classes to begin with) on the website. Is there something I am doing wrong ?
Thank you for your concern.
While the directory structure in the WooCommerce plugin itself is:
/plugins/woocommerce/templates/
You should define it like the following in your theme (note the missing templates
dir):
/yourtheme/woocommerce/
In other words, you should put all of the overrides directly within the woocommerce/
directory (there will be no templates/
directory). This is definitely confusing.
make a Woocommerce folder inside the theme directory and then follow the folder structure symmetry as in the plugin for the fallback to work properly.
Hope it will work
