How to ensure full compatibility between YayCurrency and the paid (proxy) version of GTranslate

Some users may experience the following issue when using YayCurrency together with GTranslate (paid/proxy version):

• Currency automatically reverts to the default (e.g., EUR)

• Currency changes randomly when switching languages

• Selected currency does not persist across translated pages

This behavior is not caused by YayCurrency itself, but by server-side caching from translation proxies that do not respect YayCurrency’s cookie.

The good news: ✅ YayCurrency is fully compatible with GTranslate. It just requires a simple cache configuration.

💡 Why It Worked With the Free Version

The free version of GTranslate:

• Uses client-side JavaScript translation.

• Does NOT proxy your website through their servers.

• Does NOT cache HTML on their infrastructure.

The paid version:

• Uses server-side proxy translation.

• Caches translated pages on their servers.

• Must be configured to vary cache by important cookies.

That’s why upgrading to GTranslate (paid version) introduced the issue.

Why This Happens

YayCurrency stores the selected currency in a cookie:

yay_currency_widget

This cookie ensures that:

• The selected currency persists across pages

• The correct currency loads across subdirectories and translated URLs

However, when using the proxy version of GTranslate, their server-side cache may not respect or vary by this cookie.

As a result:

• Cached pages may be served without considering the user's selected currency.

• The currency may revert to the default or behave inconsistently.

The Solution

The fix is straightforward:

👉 Ask GTranslate support to exclude the yay_currency_widget cookie from their proxy cache.

Once this cookie is excluded:

• GTranslate will not serve cached pages that ignore the selected currency.

• The currency switch will remain stable across all translated pages.

• Everything will work perfectly.

How to Fix It (Step-by-Step)

1. Contact GTranslate Support

2. Inform them that:

   • You are using YayCurrency.

   • YayCurrency stores currency in the yay_currency_widget cookie.

   • Their proxy cache must exclude this cookie.

3. After GTranslate configures this on their servers, the issue will be resolved.
