@timchannel Yes! That helps!

Can you try to do following:
1. Deactivate our plugin
2. Activate our plugin
3. Save it’s configuration

Let me know if this fixes the issue.

Thanks,
Vidish

Hey @vidishp Fails with the same error and stack trace.

Ok, can you please check following:

1. In your options table, there is an id with this meta_key “_fodw_coupon_id”
2. The id that you found in #1, does that really exist in your system? Try editing it.
3. If the id exists in #2, then can you try applying the coupon manually on your cart and see if you are able to apply the coupon?

Let me know results for above steps.

Thank you,
Vidish
