If you're using the bilingual theme but your customer pages are showing two languages and are not styled like the rest of the theme, don't worry! It's a simple fix. In Shopify there's an option for having a different layout for the customer pages, and you can change it in theme settings.
- Go to theme settings of the bilingual theme
- Expand the bottom section, "Additional Layouts"
- Change the layout to "theme" (It might take a few seconds for Shopify to populate the dropdown, be patient :) )
And now your theme should look and translate like the rest of the theme! Go get 'em!
