This is what I got. Yes it’s the CheckOut page btw and there were no errors there. It really happens only when I’m doing a test purchase under FireFox. From Chrome it’s working perfectly. It looks like for me that from FF, after the pop-up window closes, it’ somehow not returning something to the tab where the purchase has been made.
But I really don’t know. I have turned off almost all the plug-ins and it’s still the same.
This is the only log entry from WC Status:
