Hi, my customers are not able to place orders they can fill out all the details during onepage checkout but once they hit "place order" nothing happens. This problem just occured a few hours ago and was working perfectly fine before. I see that others had an issue with mbstring but this cannot be for my case since place order has always been working.
Can someone pelase advise what I can try?
