Good afternoon. I have a question. I want to do a one page site exactly as the one we have in http://sungtelrecycling.com but in Spanish. Is there a way to copy the whole site so I can change the words from English to Spanish or should I create another WordPress installation and install the theme again and do it in Spanish? Any suggestion will be greatly appreciated.
There are two (actually three) possible ways to solve this.
1. Option: Use a multi-language plugin.
This is the most common multi language setup. The most widely used (payed) plugin for multilanguage is WPML, which we recommend. As a free alternative I can also recommend Polylang.
The pages can be easily copied and translated using any of the two plugins.
If you choose to use WPML, I also recommend this plugin for the widget in sidebars: https://wordpress.org/plugins/wpml-widgets/
2. Option: Create a separate site on a subdomain
You can copy the existing WordPress database and files to a subdomain, then edit wp-config.php file and add this two lines inside:
(change example.com with your subdomain).
Now you have two identical copies of WordPress. You can add link to a Spanish version on the English site and link to English version on the Spanish site. (You can turn on top-bar in theme options and add this links there - or anywhere you want).
You can use Loco Translate plugin to translate various theme strings (like "search", "next/previous post", etc) to Spanish... More info here: https://orionthemes.com/knowledgebase/how-to-translate-a-wordpress-theme-into-your-language/
3. Option: Multisite (not recommended in case of existing site)
WordPress also has the possibility to install it as Multisite, in which case it works similar as two separate sites, but I can't recommend it in your case, as changing a normal installation to a multisite is not easy and reliable. - You might loose the content. If you go this way, make sure you create a full backup before. More info on WordPress multisite can be found here: https://codex.wordpress.org/Create_A_Network
Using a plugin might be a better solution, as you can link subpages between different languages and also you have only one site to update and all the editing is done on a single site... On the long run it is less time-consuming to maintain. However there are also some drawbacks. This plugins are quite resource intensive and might slow down the site especially if you are on a restrictive hosting plan.
I hope this helps,Andrej
Andre, thanks for such a solid answer, final quiestions
1. Im using the one page site system, would the polylang plugin work with that type of page style?
2. Would the slider be translated too?
Sorry for all the questions, I appreciate your support.
1. Yes one page should function normally, multisite plugin should not affect any functionality.2. You can duplicate the slider and modify it to your needs, then load the new slider on the Spanish version instead of the old one.
