Otter blocks form submit no longer working

My OtterBlock contact form has stopped working. When I try to send a test email using the form, I get an error message that says “undefined” after I click the Submit button.

I tried to troubleshoot by editing the block to see if something had changed since the last time the form worked. I’m noticing any new options. I tried the option at the bottom of the block, under “advanced” to “send test email.” I get a confirmation that the test email has been sent, but I don’t actually receive anything.

I do not have a pro account, but the form worked perfectly when I set it up earlier this year. I’m not sure at what point it stopped working because I don’t test it frequently and I don’t get many submissions.

I just updated my Otter Blocks plugin to v3.0.5 thinking that an update might fix the issue. Unfortunately, I’m still getting the same error. Any help would be most appreciated. If I can’t fix this, I’ll have to stop using Otter Blocks for my form and find another option.
