Oops Something Went Wrong

Even after bringing both WP and the plugin to current release we are getting the “Oops” error only for new subscriptions. Existing subscribers get the correct “you’ve already subscribed” message.

We reviewed
https://www.mc4wp.com/kb/fix-the-oops-something-went-wrong-error/

1. There is nothing at all in the log
2. the MC interface has changed and the directions to look at the API logs do not apply, so we cannot ascertain that information.
3. The MC lists were renewed
4. We have not touched this form or the MC install since it was built; so there is no chance of it getting out of sync.

Any help would be appreciated.
