If you only have one language in your store, Glotio will not be able to do translations and will ask you to add languages in your PrestaShop. You don’t need to activate the languages in your store, just add them. So you can check the translation before showing it to your clients.
Add languages from Glotio to your store
You can access to My Language section and then to “Install a new language” in order to add languages directly from Glotio to your store. Select a language from the list and click on “Install” and wait for the installation process to finish. If you experience any problem, try the manual installation to your store in the next section.
How to add a new language to PrestaShop
The recommended way to add languages in PrestaShop is by importing a localization package that adds the language, currency, states, taxes, etc. You can do this in the PrestaShop Localization section.
You can check the official Prestashop documentation to import a localization package:
Prestashop 1.6 documentation on importing a localization package.
Prestashop 1.7 documentation on importing a localization package.
It is also possible to add a new language by entering all your data, but we do not recommend it as it is easy to make a mistake. You can check the official Prestashop documentation to add a language like this:
Prestashop 1.6 documentation to add a language.
Prestashop 1.7 documentation to add a language.
In addition, you can consult more PrestaShop documentation on the localization:
Prestashop 1.6 documentation on localization.
Prestashop 1.7 documentation on localization.
If you only had one language in your Prestashop, you should keep the following points in mind before activating more than one language in your Prestashop:
In order for your customers to select the language of your store, you must enable the Language selector module. If after activating it, you do not see it, check that you have activated more than one language in your store and reset the Prestashop cache in the "Performance" section. If you still don't see it, check your template documentation or consult an expert technician to analyze the problem.
By adding more than one language, PrestaShop modifies the URLs of your store a little. For example, if your website address was www.domain.com, it will now become www.domain.com/en/ or www.domain.com/en/ depending on the language. This is not a problem as long as you configure redirects with the value 301. In the SEO and URLS section, this will not affect your SEO since it will automatically redirect your old URLs www.domain.com to www.dominio.com/en/.
