product sync not working

Hi for some reason it appears that the auto sync for products prices and if out of stock etc has stopped working and no longer starts when scheduled and i wondered if you could take a look for me please . The date also does not change as you can see from attached photo the date has been and gone but no sync started and the date has not changed to next scheduel time. I normall set it for every 3 days but have done it for daily over last 2 days just to see if it works but it didnit .Thank you
