WooCommerce - My Account: Redirect to the wp-login page in a secondary language after logging out

Overview of the issue

If you set the Language URL format as Language name added as a parameter, you will experience that after logging out from My Account page in a secondary language, you are redirected to the wp-login.php instead of staying on the My Account page.

Workaround

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

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

  add_filter( 'logout_url', function( $url ) {
      return str_replace( '&', '&', $url );
  }, 5 ); // Priority 5 to run before WPML's Core filter.
  

Alternatively, you can turn off the Allow translating the login and registration page option in WPML > Settings page..
