Problem: The client is using WCML and has encountered an issue where Google Merchant Center is not compatible with geolocation for currencies, leading to a blockage of all products due to price mismatches. The client needs a solution to send products with different currencies to Google Merchant Center, each with a unique URL. Solution: We recommended a custom implementation using WCML hooks for multi-currency, which involves detecting a URL parameter and dynamically setting the currency. Specifically, the client can override WCML's currency selection by using a URL parameter (e.g.,
?wcmlc=USD
). This approach requires adding custom code to check for the URL parameter and conditionally override the default currency behavior. We suggested using the
wcml_client_currency
filter or a similar hook for this purpose. Additionally, we advised against using geolocation for this specific use case as it conflicts with Google Merchant Center requirements.

Problem: You are experiencing issues with the currency switcher not working correctly in conjunction with geolocalisation and caching. You've noticed that changing the currency by altering the country in the billing address doesn't update as expected, and using a VPN to change currencies results in cache misses. Solution: We've investigated the issue and found that the problem stems from the currency settings configured on your site. Specifically, CAD is only available in Canada, and USD is available in all countries except Canada. This configuration means that there is no region where two currencies are available simultaneously, rendering the currency switcher ineffective in your current setup. To resolve this, you might need to adjust the availability settings of your currencies to ensure that more than one currency is available in the regions you are targeting.
