You need to enter text in the expiration date area instead of a date if there is no expiration date.
Aside from that, it’s possible this was conflicting with the theme or another plugin because it is working fine for other users.
I have almost the same problem. My coupouns with an expire date are get trashed automatically (after filling in the expiry date and saving my coupon, it says this: Jan 01, 1970 00:00. What can I do to fix this? The ones without an expire date are working really good.

Hello, I’m sorry you are experiencing that. We will look to fix this in our next update but we can’t give an expected time estimate at this stage, I’m afraid. Again, it’s possibly conflicting with another plugin on your site so in the meantime you could try disabling other plugins individually.
