This great plugin has been working perfectly for a couple of years now. However within the last few days, when clicking on WooCommerce > Orders, the order numbers appear to be generating incorrectly. Previously they were listed by successive invoice number order/chronologically. Clicking on the Order up-caret puts them in reverse order then clicking on the Order down-caret arranges them correctly by invoice/chornological order.
Welcome your expert advice to resolve this for my client. TIA!
