 * Since our upgrade to PHP8 this plugins stops working. Here is the log message:
 *     ```wp-block-code
       PHP Fatal error:  Uncaught TypeError: implode(): Argument #1 ($pieces) must be of type array, string given in /(...)/plugins/subscriber-discounts-for-woocommerce/includes/create-discount.php:138
       ```
   
 * I fixed that (without further investigation) by testing for arrays. Here is the
   git diff:
 * [[
 * There might be a better solution. Could you please fix that?
 * Anyway, thanks for the great plugin!
