LiteSpeed Cache - Unable to switch to the default currency after switching to another currency

Overview of the issue

When using LiteSpeed Cache with WPML Multilingual & Multicurrency for WooCommerce and the multicurrency feature, switching back to the default currency after selecting a secondary currency may not work correctly. The currency remains stuck, and you need to repeat the operation twice to make it work.

Workaround

Please, make sure of having a full site backup of your site before proceeding.

• Add the following code to your theme’s functions.php file.

  // WPML - Use Cookie instead of WCSession
  add_filter( 'wcml_user_store_strategy', function ( $strategy, $key ) {
      return 'cookie';
  }, 10, 2 );
          

• Go to to “LiteSpeed Cache > Cache > Advanced > Vary Cookies“.
• Add the following cookie: wcml_client_currency
