This very simple WordPress plugin automatically sets up the WP language environment based on the first part of the url of any page.
It will automatically setup the right XML header lang attribute + the internal WordPress $locale variable that is used to load the right language files for i18n and l10n (.po, .mo).
<h4>Usage:</h4>
Your blog URL structure should always begin with an official two-letter langage code, for example:
<ul>
<li>/en/… for english</li>
<li>/es/… for Spanish</li>
<li>/ja/… for Japanese</li>
<li>/fr/… for French</li>
<li>etc.</li>
</ul>
Please use only lower-case codes.
Pages that don’t comply to this URL scheme will still get your blog’s default locale setting, as configured in your wp-config.php file.
Sometimes you need to rename or copy some of your po/mo files, for example French language PO files are usually named like this: <code>fr_FR.po</code>; 
just copy it to <code>fr.po</code> to make it work with a two-letter code.
<h4>Example</h4>
This plugin is used for extended multi-language support on the <a href="http://post2peer.com/about" title="Post2Peer posts and sites directory" rel="nofollow ugc">Post2Peer.com open posts directory</a>.
<h4>Français</h4>
Ce plugin permet très simplement de faire fonctionner un blog multilingue ou bilingue, français/anglais par exemple.

Built to remove barriers
Global ecommerce is hard—regulatory complexity, surprise costs, and fragmented tools create friction for your team and your customers. Checkout replaces the guesswork with a localized experience that handles duty, tax, shipping, fraud protection, and restricted items behind the scenes—so your shoppers get a seamless checkout, and your business can expand globally with confidence.
Why merchants choose Zonos Checkout for WooCommerce
Checkout was built to solve international ecommerce challenges, where trust is hard to earn. From the first moment a shopper lands on your site to the moment their order arrives, every part of Checkout works together to create a localized, low-friction experience while keeping you in control of what matters most: your brand, your margins, and your customer relationships.
<h4>Features</h4>

Engage shoppers with Zonos Hello – Shoppers bounce fast. Zonos Hello greets them in their own language and automatically adapts your site to their currency—giving them instant confidence that you ship to their location before they even start browsing. Configurable with country-specific custom messages.

<li>
Make global shoppers feel at home – Checkout automatically carries over the shopper’s language and currency, creating a smooth, localized checkout experience from browsing to payment. Local payment methods are built in, so shoppers can pay the way they’re used to.

Stay in control of shipping – Who you choose to ship with is crucial to your customer experience—and your bottom line. Zonos lets you use your preferred carriers and negotiated rates. Our advanced shipment rating provides dimensional weight, cartonization, and custom shipping logic, allowing you to confidently manage shipping incentives without cutting into your margins.
</li>
<li>
Prevent restricted item issues – Shipping restricted items can lead to customs seizures, delays, and costly support issues. Zonos removes restricted products at checkout, seamlessly avoiding these issues and ensuring customs compliance.
</li>
<li>
Avoid surprise fees at delivery – Surprise fees at delivery damage customer trust and create costly support headaches like returned or abandoned packages. Zonos provides duty and tax calculation (including tariffs) at checkout, and guarantees that no additional costs will be due. We cover any differences, protecting your customers and your margins. Plus, fewer rejected packages reduce the strain on your customer support team while increasing customer satisfaction.
</li>
<li>
Stay compliant—without the risk – Staying compliant with constantly changing global tax schemes is time-consuming and risky. With Zonos, you’re instantly compliant without even thinking about it. Zonos handles tax registration and remittance, assuming liability for low-value tax schemes like UK VAT, IOSS, and others—including any that may emerge—so you can stay focused on growth, not global tax requirements.
</li>
<li>
Protect against international fraud – Cross-border fraud is complex and costly. Zonos Checkout includes built-in fraud protection designed specifically for international transactions—screening orders based on country-specific risk, shipping patterns, and other fraud signals. If a fraudulent order slips through, Zonos covers the loss. You stay protected, and your shoppers get a seamless, secure experience.
</li>
<li>
Automate U.S. sales tax – U.S. sales tax involves thousands of state, county, and city tax rates, complicating compliance. Zonos, as your merchant of record, handles every detail—accurately calculating, collecting, and filing—so you stay compliant without the stress.
</li>
<li>
Simplify your tech stack – Managing a global business often requires a combination of apps, plugins, and manual workflows to communicate between them. Zonos eliminates this complexity by consolidating a localized checkout experience, international payment processing, fraud protection, order management, tax compliance, shipment label creation and commercial invoice management into one streamlined product—reducing cost and operational overhead across your business.
