 * **Deprecated**: Return type of FS_Key_Value_Storage::offsetExists($k) should 
   either be compatible with ArrayAccess::offsetExists(mixed $offset): bool, or 
   the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress
   the notice in **/——/wp-content/plugins/wc-place-order-without-payment/freemius/
   includes/managers/class-fs-key-value-storage.php** on line **309**
